The terminology used in this report is based on historical usage. Militia refers to military forces composed of armed citizens
raised under the authority of their state, territory, or the District of Columbia. After the Civil War, many states renamed their
organized militia forces as the National Guard, and this name was codified in law with the Militia Act of 1903. Federal
armed forces refers to military forces raised under Congress’s constitutional authority to “raise and support Armies” and “to
provide and maintain a Navy.”

Militia, National Guard, or Federal Armed Forces Use in D.C. Prior to2020

Introduction
This report provides information on 10 instances in which the militia, National Guard, or federal
armed forces were used for operations within the geographic boundaries of Washington, D.C.,
due to violence or anticipated violence. Congress may find these cases helpful when considering
the contemporary or future role of the National Guard and federal armed forces in the nation’s
capital.
CRS identified the selected events based on a search of newspaper accounts, books, and other
historical sources, but this report should not be considered a comprehensive listing of such events.
In this product, CRS does not offer deep historical context to these events or analysis that links
these events to contemporary events. The selected events do not include certain uses, such as
natural disaster response, counterdrug operations, Weapons of Mass Destruction Civil Support
Team operations, general crowd and traffic control support, most inaugural support, and
ceremonial events.1
Terms
For the purpose of this report, the terms militia, National Guard, and federal armed forces have
the following meanings based on statutory texts:
 Militia refers to armed forces composed of citizens, raised under the authority of their
state, territory, or the District of Columbia. The Militia Act of May 8, 1792, provided
in part:
That each and every free able-bodied white male citizen of the respective states, resident
therein, who is or shall be of age of eighteen years, and under the age of forty-five years
(except as is herein after excepted) shall severally and respectively be enrolled in the militia
by the captain or commanding officer of the company, within whose bounds such citizen
shall reside, and that within twelve months after the passing of this act.2
Members of the militia who trained regularly as part of militia units were sometimes
referred to as the organized militia.3

services/service/ll/llsl//llsl-c2/llsl-c2.pdf. The militia concept, derived from a long-standing English tradition, existed in
the American colonies prior to the adoption of the Constitution. The Constitution recognized the existence of the militia
and gave the federal government limited authority over it, including the ability to call the militia into federal service in
certain circumstances (Article I, §8, cls. 15, 16; Article 2, §2).
3 Current federal law maintains a distinction between the organized militia and the unorganized militia.
10 U.S.C. §246. Militia: composition and classes
(a) The militia of the United States consists of all able-bodied males at least 17 years of age and, except as provided in
section 313 of title 32, under 45 years of age who are, or who have made a declaration of intention to become, citizens
of the United States and of female citizens of the United States who are members of the National Guard.

 National Guard is the term used, beginning in the late 19th century, to refer to the
organized militia of the states, territories, and the District of Columbia. After the
Civil War, many states renamed their organized militia forces as the National Guard.
Congress adopted the term in the Militia Act of 1903:
That the militia shall consist of every able-bodied male citizen of the respective States,
Territories, and the District of Columbia, and every able-bodied male of foreign birth who
has declared his intention to become a citizen, who is more than eighteen and less than
forty-five years of age, and shall be divided into two classes-the organized militia, to be
known as the National Guard of the State, Territory, or District of Columbia, or by such
other designations as may be given them by the laws of the respective States or Territories,
and the remainder to be known as the Reserve Militia. 4
 Federal armed forces refers to military forces raised under Congress’s constitutional
authority to “raise and support Armies” and “to provide and maintain a Navy.”5 The
Army, Navy, Marine Corps, Air Force, Space Force, and Coast Guard constitute the
federal armed forces today.6
The District of Columbia
The U.S. Constitution grants Congress exclusive legislative jurisdiction over a district meant to
be the seat of the government of the United States.7 Congress had selected and acquired a district
by 1789, but it did not assume legislative authority over it until the first D.C. organic act became
law in 1801 (an organic act is legislation that confers the powers of government upon a territory).8
The act subdivided D.C. into two counties: Washington County, which included what is now
Washington, D.C., and Alexandria County, which included what is now Arlington County,
Virginia, approximately.9 Congress established the District of Columbia militia in 1803; in 1889
Congress repealed the 1803 legislation and replaced it with legislation that reorganized the
District’s militia.10 The 1889 legislation is the source for the D.C. Code provisions that currently
govern the District of Columbia National Guard (DCNG).11 For additional information on the

1814 – War of 1812
On August 24, 1814, British military forces routed a U.S. force of approximately 5,000 soldiers,
including militia, near the town of Bladensburg, MD.12 The U.S. forces retreated through the
District of Columbia and the pursuing British burned public buildings including the Capitol and
the White House.13 According to the D.C. National Guard website:
The fledging D.C. Militia was tested during the War of 1812. Maryland and Virginia, pre-
occupied with attacks on their own territory, were sluggish to send troops to D.C. The D.C.
Militia, even when augmented by regular forces, was overwhelmed and ordered to
withdraw. They watched the nation’s capital burn. After this incident, Congress took notice
and increased the size and equipage of the D.C. Guard.14

1857 – Know-Nothing Riots
The American Party, sometimes known as the Know-Nothing Party, was an organization that
emerged in the 1840s out of a secret organization and was known for its nativist and anti-
immigrant agenda; there were also anti-slavery elements in the northern wing of the party.15, 16
The party sought to restrict political power to native-born Protestants, eliminate Catholics from
public office, and extend naturalization laws from five years to 21 years. Members were required
to be native-born Protestant citizens.17 Support for the Know-Nothing cause increased in the
1850s as immigration to the United States grew.18

During a municipal election in June 1857 in Washington, D.C., the Know-Nothing party hired
gangs to intimidate voters at the polls, a common practice at the time.19 On June 1, 1857, as
voters lined up at the polling stations near Mount Vernon Square and Pennsylvania Avenue NW,
they were attacked by street gangs such as the “Plug Uglies” and “Rip Raps” that had come into
the city from Baltimore.20 Local police were overwhelmed by the mobs.21 At the request of the
mayor, President James Buchanan ordered a Marine detachment to help restore peace.22 Led by
Captain A. B. Tyler, 115 Marines marched throughout the city and confronted the gangs. Colonel
Archibald Henderson, the Commandant of the Marine Corps, was also on the scene in civilian
clothes.
The Plugs had brought their stolen cannon to the polls. Bracing its wobbly wheel and
loading it with rocks, nails, bullets, and other shrapnel, they aimed the weapon at the
polling booth. Two of the rioters threatened to fire the cannon if Tyler didn't leave his
position. "Then I will take your cannon," the captain snapped.
Meanwhile, Colonel Henderson, "dressed in citizen's dress," had found a place within the
mob. He began edging his way toward the cannon and urged the rioters not to fire. Then
he put himself in front of the cannon's mouth. "I approached it and placed my knee against
it with a determination to prevent its being fired until the Marines could get to the place
where I wished them to be," Henderson said later. Exploiting the cannon's wobbly wheel,
he knocked it to one side. Luck, in the form of rain, was with Henderson that day. A rioter
named Charlie Hurdle rushed forward and thrust his cigar into the cannon's touchhole, only
to see it fizzle in the damp. With the Marine column safe from the weapon, Henderson
slipped across the intersection and whispered to Captain Tyler, "It's time to take it."
One Marine company charged with fixed bayonets, with Henderson in its midst, carrying
only his cane, crafted from the wood of a British warship he had battled during the War of
1812. The leathernecks scattered thugs and bystanders alike. The Plugs raced for the
railroad, followed closely by Marines. Faced with armed troops instead of defenseless
voters, the Plugs piled aboard their trains and headed back to Baltimore. On the way, they
passed the southbound train bearing Major French's Flying Artillery from Fort McHenry,
rushing to secure the capital.
The polls at the disturbed precincts reopened in the afternoon, and voting continued
undisturbed. But five people had died and 15 were wounded, mainly peaceable citizens.23
A contemporary news article indicates that the Plug Uglies fired pistols during the charge, and
“the marines fired in two directions, one company discharged their pieces at those in command of
the gun, and the other at the crowd at the northwest corner of Seventh and K streets.”24 The use of
force by the Marines that day was called into question, with one historian claiming that most of
the actions by the Marines took place when no violence was going on.25 The U.S. Attorney for the
District of Columbia prosecuted six riot leaders who had been captured, and all were convicted
and sentenced to a year in jail and $20 fines.26

1861-1865 – Civil War
After the election of Abraham Lincoln, on November 6, 1860, but before he was inaugurated on
March 4, 1861, seven states seceded from the United States.27 Situated between Virginia and
Maryland, both slave states, the District of Columbia was in a precarious position.28 After
consulting with President Buchanan, Brevet Lieutenant General Winfield Scott appointed Colonel
Charles Stone to improve the defenses of Washington, and produced a militia force of “thirty-
three companies of infantry and riflemen and two troops of cavalry [who] were on the lists of the
District volunteer force; and all had been uniformed, equipped, and put under frequent drill.”29
Federal armed forces were brought to the District as well:
Regular Army units of all arms–infantry, cavalry and artillery as well as Engineer Sappers
and Miners–responded to [General Scott’s orders] and on February 12, the day before the
electoral college met, they were guarding the principal government buildings–White
House, Treasury, Capitol, Patent Office and Post Office. The next day they kept an unruly
mob, composed of Maryland, District of Columbia and Virginia southern sympathizers,
from disrupting the deliberations of the electoral college or creating mischief in general….
Inaugural day arrived and many were apprehensive. Riflemen were posted along the parade
route and in the Capitol. Artillery, cavalry and various other military units took station at a
variety of points along the route, but out of the citizens' view, to counter any possible mob

violence. Unbeknownst to most of the spectators, local militiamen protected the inaugural
platform.30
While the inauguration of President Lincoln was completed without incident, the Civil War began
on April 12, 1861, with the Confederate attack on Fort Sumter. Throughout the Civil War, federal
armed forces, including militia units called into federal service, were a constant presence in the
District of Columbia. A portion of these forces was dedicated to the defense of Washington, D.C.,
manning a series of forts and artillery batteries surrounding the capital.31

1917 – World War I Homeland Defense
According to the DCNG, “Fearing espionage, the D.C. National Guard was recalled to active duty
seventeen days before the U.S. officially entered WWI to protect reservoirs and power plants
around the city.”32 According to newspaper accounts from the time, the activation appears to have
occurred in late March 1917 and consisted of several battalions, one of which was assigned to
guard an aqueduct that delivered water to the District from Virginia.33
1919 – Washington, D.C. Race Riots
In late June and early July 1919, “several attempted rapes of white women were reported in the
District of Columbia and surrounding areas.”34 Police were convinced that a single Black
perpetrator was responsible, though many Whites believed “a premeditated epidemic of sexual
assaults by blacks upon area white women was under way.”35 Local newspapers sensationalized
the allegations.36 On July 19, a White mob that included off-duty military personnel (and perhaps
recently discharged World War I soldiers in uniform) assaulted a number of Black men; the mob
grew and attacks expanded the following night.37 On July 21, Black residents took up arms to
defend their neighborhoods.
Black residents suspected the target that night would be LeDroit Park, the prosperous black
neighborhood next to Howard University. Two thousand black veterans and their
compatriots formed a line of defense down Florida Avenue/U Street from 6th to 14th
streets, facing south. They were armed.

Militia, National Guard, or Federal Armed Forces Use in D.C. Prior to2020

As the sun set, Krugler wrote, skirmishes broke out. A white mob chased a black delivery
driver; a band of black men boarded streetcars and assaulted uniformed Marines.... It
continued like this through the short summer night.38
President Woodrow Wilson directed federal armed forces to restore order. Major General William
Haan, director of the Army’s War Plans Division, employed a force of about 1,000 soldiers and
Marines, 85 cavalrymen, and some military intelligence personnel.39 According to authors
Clayton D. Laurie and Ronald H. Cole:
With ample power at hand, Haan quickly set about to restore order in the district. Instead
of acting simply in support of the district police, federal troops assumed primary
responsibility for law enforcement. The creation of a unified command placed law
enforcement forces under Army direction and control … in general the saturation of trouble
spots with federal troops quickly succeeded in restoring order. By Thursday, 24 July 1919,
rioting in Washington, D.C., had ended, and the Army indicated its strong desire to return
law enforcement responsibilities to the district police. Larger federal units left Washington,
D.C., on 27 July, while a smaller Army detachment of thirty-five officers and men of the
63d Infantry remained in the city to support police forces until the following day, when
they too were withdrawn.40
1932 – Bonus Marchers41
In 1924, Congress approved bonuses for World War I veterans, payable in 1945. In 1932, in the
midst of the Great Depression, Congressman Wright Patman introduced a bill to make the bonus
payable immediately. Approximately 10,000 to 20,000 veterans arrived in Washington, D.C.,
from across the nation to pressure Congress to pass the bill, living in shantytowns they built near
the Capitol and in Anacostia. The bill passed the House, but not the Senate.42 Congress adjourned,
but the veterans remained and conducted demonstrations on the Capitol steps and in front of the
White House. Police attempting to evict the protesters from vacant buildings were met with
resistance and the Board of Commissioners of the District of Columbia requested military support
from President Herbert Hoover. Secretary of War Patrick Hurley argued that the “mob defiance
constituted insurrection and that the marchers represented the vanguard of a Communist
revolution, [but] Hoover flatly refused to proclaim a state of insurrection or to declare martial
law.”43 Hoover did approve the use of federal armed forces to assist the police operations in a
supporting role, but Army Chief of Staff General Douglas MacArthur deviated from these
restrictions and had the military directly remove the marchers from the District. According to
authors Laurie and Cole:
Led by a one-star general, a column of nearly 200 mounted cavalrymen, 300 infantrymen,
and 5 tanks advanced southeast from the Ellipse, down Pennsylvania Avenue, toward 3d
Street, Northwest, at the base of Capitol Hill.… Accompanying the column in a staff car,

Militia, National Guard, or Federal Armed Forces Use in D.C. Prior to2020

Army Chief of Staff General Douglas MacArthur prepared to evict from the city a ragtag
group of unemployed veterans known as the Bonus Expeditionary Force.44
Soldiers used tear gas to disperse crowds of marchers and bystanders. Later, cavalry “struck with
the flat of their sabers, while the infantry, arriving at the scene, prodded the crowd with
bayonets.”45 It is not clear why MacArthur exceeded his orders, but he appears to have shared
Hurley’s belief that the marchers were infiltrated by communists intent on overthrowing the
government.46 MacArthur subsequently ignored orders from President Hoover forbidding him to
cross the bridge to the Anacostia site where, though crowds harassed the troops en route, the
troops cleared the final protesters’ location in what was ultimately a “bloodless” operation.47

45 Laurie and Cole, The Role of Federal Military Forces in Domestic Disorder, 1877-1945, p. 380.
46 “Why MacArthur embarked on this course remains far from clear. He had confided his presidential ambitions to
close friends and may have believed that a low-key form of military intervention, if it failed, would make him appear
too weak and indecisive for the nation's highest office. Believing the rumors and reports of Communist revolutionary
intent, MacArthur may have seen a complete rout of the marchers as the best way to prevent an uprising then or in the
future. Finally, he may have hoped to convince Congress that in a world rocked by depression, dictators, and
revolutionaries the Army was crucial to internal stability and therefore merited increased appropriations” and
“According to one biographer, ‘Once MacArthur was convinced that the affair was a Communist assault against the
federal government, he acted with overzealous determination and reckless impulsiveness.’” Laurie and Cole, The Role
of Federal Military Forces in Domestic Disorder, 1877-1945, pp. 377, 383.

1967 – Vietnam War Dissent Demonstration and Riot
On August 28, 1967, the National Mobilization Committee to End the War in Vietnam announced
a planned demonstration to block the entrances to the Pentagon.48 The plan for the protest
included a rally at the Lincoln Memorial and a march across the Memorial Bridge to another rally
at the Pentagon, followed by acts of civil disobedience.49

In anticipation of the event, there were 12,000 federal civilian and military personnel at the
Pentagon and on call in the national capital area.50 This included almost the entire DCNG (about
1,700 personnel).51 Plans published nine days before the event indicated that the DCNG would
primarily work with police in the District performing crowd and traffic control, “but a 202-man
force would accompany a riot-trained police reaction force, dressed similarly in field uniforms
and steel helmets and carrying gas masks and weapons. Another 90 would guard several
important government buildings in Washington.”52 The plans also indicated there would be three
active duty Army battalions stationed at the Pentagon, along with four military police companies,
additional military personnel to augment the Pentagon’s guard force, and a five battalion reaction
force in the Washington area.53 A brigade sized task force from the 82nd Airborne Division was
moved to Andrews Air Force base shortly before the demonstration as well, and there was a
Marine contingent located at Anacostia Naval Station.54 The Army also infiltrated the
demonstrators with undercover military intelligence agents in the cities where they assembled and
conducted electronic surveillance during the protests.55
On October 21, 1967, tens of thousands of demonstrators assembled near the Lincoln Memorial
in Washington, D.C.56 There were a few arrests at the Lincoln Memorial rally, but a violent
confrontation occurred after protesters marched from the Lincoln Memorial to the Pentagon.57
Historian Paul Scheips describes the Pentagon scene as follows:
The first confrontation with the soldiers came about 1600 [4 p.m.], when some 200 demon-
strators armed with “ax handles and carrying gas masks” breached a fence separating the
North Parking area from the Jefferson Davis Highway and made for the River entrance.
Marshals made arrests, but as the crowd grew in that area it moved toward the Mall
entrance where upwards of a thousand threatened and then broke the rope barrier. In
response, the authorities deployed a reserve company of the 503d Military Police Battalion

54 Scheips, The Role of Federal Military Forces in Domestic Disorders, 1945–1992, pp. 251, 264.
55 In anticipation of the event, General Harold K. Johnson, the Army Chief of Staff “...instructed military intelligence
personnel to join contingents of demonstrators and to travel with them by bus and train to Washington ‘to develop
timely information on aims, movement, tactics and leadership of participating organizations and groups’... [undercover]
Agents who maintained their cover were well received by the demonstrators, and sometimes played important roles
among them. One, for example, served as the leader of a busload of demonstrators.” Scheips, The Role of Federal
Military Forces in Domestic Disorders, 1945–1992, pp. 242-43. The Army Security Agency also monitored radio
frequencies during the march, and “[i]n an unprecedented action on 20 October, General Yarborough, the assistant
chief of staff for intelligence, sought and obtained National Security Agency support of the Army’s civil disturbance
mission.” Scheips, The Role of Federal Military Forces in Domestic Disorders, 1945–1992, pp. 248.
56 According to Paul Scheips, “Estimates of the crowd’s size were contradictory and impossible to reconcile. The
[Military District Washington] headquarters put the number of persons at the Lincoln Memorial at 30,000 to 35,000,
while the District of Columbia police estimated 20,000 to 22,000—although it may have been as large as 75,000. On
the basis of counts made by two different intelligence agencies, the military district believed that approximately 33,000,
‘including a considerable number of sightseers,’ crossed the Memorial Bridge on their way to the Pentagon, while the
Department of the Army put the number at 20,000.” Paul J. Scheips, The Role of Federal Military Forces in Domestic
Disorders, 1945–1992 (Washington, DC: United States Army Center of Military History, 2012) pp. 255, available at

to that location. To restrain the shoving throng, marshals arrested those demonstrators who
failed to fall back quickly....
Military police reinforcing the Mall entrance appeared briefly with rifles and bayonets
fixed and sheathed. Since authority had never been given for the bayonets, [Army Chief of
Staff] General Johnson ordered them removed. By 1700 [5:00 p.m.], the temper of the
demonstrators around the entrance seemed to approach hysteria. Individuals surged against
the troops, shouting curses, throwing bottles and rocks, and slashing with picket signs
bearing antiwar messages. An aggressive element of the crowd attempted to go around the
roadblock at the Washington Boulevard entrance to the Mall in an apparent effort to reach
the Pentagon’s heliport. That effort failed, but angry demonstrators at the Mall entrance
nearly broke through the restraining line there. In response, commanders reinforced the
troops both at the Mall and at the roadblock....
About that time, a thousand or so demonstrators swept around the northeast corner of the
Mall parking lot and advanced on the River entrance, prompting the movement shortly
after 1730 [5:30 p.m.] of a provisional battalion from Fort Myer to the Pentagon. In an
explosion of violence, other demonstrators overran a platoon of military police located to
the right of the Mall steps. Some of the soldiers were knocked to the ground. It was at this
time that Attorney General Clark released the decision-making authority for using troops
to General Johnson. But by then the assault on the Pentagon had reached its peak, with
approximately 2,000 people breaking through the restraining line and charging toward a
door to the left of the main Mall entrance. Only twenty or thirty pressed their way into the
vestibule, and they were immediately and roughly pushed back to the bottom of the
entrance stairway by troops inside the building....
As the afternoon waned, the turbulence caused commanders to urge stronger action.
Whatever violence occurred, however, was the work of a minority. Task Force Inside [the
main active duty element] would later report that “there were probably fewer than 500
violent demonstrators,” although they “were backed by from 2,000 to 2,500 ardent
sympathizers.” Overall, from 85 to 90 percent of the crowd appeared to remain peaceful
throughout the demonstration.
Published accounts of the day’s activities contained a number of credible reports about
military policemen and marshals who clubbed some demonstrators, and of soldiers who
used their boots and rifle butts.58
1968 – Martin Luther King Jr. Assassination Riots
At 4:00 p.m. on April 5, 1968, the day after the assassination of Reverend Doctor Martin Luther
King, Jr., the D.C. mayor requested federal troops to assist civil authorities in their response to
riots in the district. At 4:02 p.m., President Johnson issued a proclamation to “command all
persons engaged in such acts of violence to cease and desist therefrom and to disperse and retire
peaceably forthwith.”59 (A proclamation to disperse is required before a President may rely on
Chapter 13 in Title 10 of the U.S. Code to quell a riot).60 The statutory notice had been in effect
for one minute when the President issued Executive Order (EO) 11403 at 4:03 pm to provide “for
the restoration of law and order in the Washington Metropolitan Area.”61 The EO authorized the

Secretary of Defense to federalize, and assume authority over, the National Guard for an
indefinite period to carry out the EO’s purposes. The order also gave the Secretary of Defense
authority over the DCNG in its militia status, but 57 minutes later, this authority went unused as
the Secretary exercised the Order’s primary delegation to federalize the DCNG at 5:00 p.m.62
DCNG duties during the riots included providing security for the U.S. Capitol. The total number
of troops deployed in D.C. soon after the issuance of EO 11403 was 13,466. This number
included 11,618 from the active Army and 1,848 from the National Guard.63 Total strength in the
District peaked on April 10, 1968, at 15,530 troops.64

1971 – May Day Protests
On May 1, 1971, thousands of protesters, led by a group called the Mayday Tribe, marched in
Washington, D.C., against the Vietnam War. The march occurred after several weeks of
antiwar demonstrations in Washington, D.C.65 The Mayday Tribe set up a large, federally
permitted, encampment near the Lincoln Memorial and organized protests in the city with the
intent to block traffic and hinder federal employees trying to get to work.66 The May Day

Tribe slogan was “if the government won’t stop the war, we’ll stop the government.”67
According to one news account:
The official scenario, devised by the Mayday Tribe, a militant component of the Peoples
Coalition for Peace and Justice, calls for groups ranging from 1,000 to 3,000 persons each
to march to 21 selected locations in downtown Washington and suburban Virginia at about
7 a.m. Monday and Tuesday [May 3rd and 4th]. They hope to block all major commuter
traffic for several hours and thus halt the functioning of government.68
On June 30, Deputy Attorney General Richard Kleindienst announced that a force of 7,300 police
and National Guard personnel were being readied to respond to the traffic disruptions planned by
the protestors.69 The force included approximately 5,000 D.C. Metropolitan Police, 1,400
National Guardsmen, 450 U.S. Park Police, and 450 United States Capitol Police.70

On May 2, the Department of Justice revoked the Mayday Tribe’s license to use the parkland near
the Lincoln Memorial and police went into the encampment at around 6:30 a.m. to clear out the
protestors.71 The Washington Post reported that police cleared about 45,000 people from the park,
although up to 10,000 regrouped in other parts of the city.72 At the same time, the federal
government brought in about 10,000 more troops, including 2,000 Marines from Camp Lejeune,
NC, and 4,000 paratroopers from the Army’s 82nd Airborne Division at Fort Bragg, NC.73
Throughout the day, “four-engine C-130 transport planes landed at Andrews [Air Force Base],
unloaded battle-dressed paratroopers, and then took off again without halting their engines for
return flights to North Carolina and more troops.”74 On Monday, May 3, demonstrators headed to
key intersections, bridges, and traffic circles to form barricades with items such as wood, metal
poles, and parked cars.75 That day, “more than 7,000 persons were arrested in widespread hit-and-
run skirmishes with police and federal troops ... [t]he arrests, made while police fired tear gas
through much of downtown Washington and military helicopters whirled across city skies, were
greater in number than any single event in the nation’s history, research indicated.”76 On May 4,
coalition leader Rennie Davis was arrested by the Federal Bureau of Investigation on conspiracy
charges. The protests ended on May 6, and over 12,000 people were arrested.77
2001 – Post-9/11 Homeland Defense Activities
In the days that followed the September 11, 2001, terrorist attacks on the Pentagon in Virginia and
the World Trade Center in New York, the DCNG mobilized personnel for security duty
throughout Washington, D.C. The DCNG also established Task Force Capital Guardian with 100
National Guard personnel responsible for providing perimeter security at the U.S. Capitol
Complex. Specific duties included securing the restricted area around Capitol Hill and checking
vehicles entering that area.78
