U.S. Periods of War and Dates of CurrentRecent Conflicts
Summary
Many wars or conflicts in U.S. history have federally designated “periods of war,” dates marking
their beginning and ending. These dates are important for qualification for certain veterans’
pension or disability benefits. Confusion can occur because beginning and ending dates for
“periods of war” in many nonofficial sources are often different from those given in treaties and
other official sources of information, and armistice dates can be confused with termination dates.
This report lists the beginning and ending dates for “periods of war” found in Title 38 of the Code
of Federal Regulations, dealing with the Department of Veterans Affairs (VA). It also lists and
differentiates other beginning dates given in declarations of war, as well as termination of
hostilities dates and armistice and ending dates given in proclamations, laws, or treaties. The
dates for the recent conflicts in Iraq and AfghanistanAfghanistan and Iraq are included along with the official end date for
for Operation New Dawn in Iraq on December 15, 2011, and Operation Enduring Freedom on
Afghanistan on December 28, 2014. This report will be updated when events warrant.

U.S. Periods of War and Dates of CurrentRecent Conflicts
War Dates
Congress, usually through a declaration of war, has often been the first governmental authority to
designate the beginning date of a war or armed conflict. The President, or executive branch
officials responsible to him, through proclamation, or Congress, through legislation, havehas been
responsible for designating the war’s termination date.1 In some cases, later legislation is enacted
to extend these beginning and ending dates for the purpose of broadening eligibility for veterans’
benefits.2 This report notes the variations in the dates cited in the Code of Federal Regulations
(CFR) “periods of war” and those dates given in the declarations of war beginning and the
proclamations, laws, or treaties terminating such conflicts.3 Adding to the confusion, during World
World War II, wars were declared and terminated with six individual combatant countries.
Moreover,
armistice dates are also often confused with termination dates.34
Title 38, Part 3, Section 3.2 of the Code of Federal Regulations, dealing with the Department of
Veterans Affairs (VA), lists official beginning and termination dates for most war periods from the
Indian Wars to the present to be used in determining the availability of veterans’ benefits.45 The
material below summarizes these dates. Where applicable, a summary of the Department of
Veterans Affairs official beginning and termination dates is provided followed by a citation to the
lettered CFR section. For some entries, this initial summary is followed by an explanatory note or
declaration, armistice, cease-fire, or termination dates cited by other official sources. Also
included are dates for the currentrecent conflicts in Iraq and Afghanistan.
Indian Wars
January 1, 1817, through December 31, 1898, inclusive. Service must have been rendered with
U.S. military forces against Indian tribes or nations. Code of Federal Regulations, 3.2 (a).
Spanish-American War
April 21, 1898, through July 4, 1902, inclusive. If the veteran served with the U.S. military forces
engaged in hostilities in the Moro Province, the ending date is July 15, 1903. The Philippine

Title 38 of the CFR, titled “Pensions, Bonuses and Veterans’ Relief,” is not to be confused with Title 38 of the United
States Code, titled “Veterans Benefits.” Laws enacted in each Congress are first collected as session laws, published in
the Statutes at Large for each session. These laws are then codified by subject and published in the United States Code.
The general guidance given by these laws results in the issuance of more detailed regulations to implement these laws.
Such regulations are first published in the Federal Register and are then codified by subject in the CFR.

World War II with Germany
Declared by Joint Resolution of Congress, December 11, 1941 (55 Stat. 796, ch. 564). German
representative Colonel General Alfred Jodl signed the unconditional act of surrender to Allied
representatives in a Reims, France schoolhouse on May 7, 1945. A second German surrender
ceremony was held on May 8 in Berlin at the insistence of the U.S.S.R. Cessation of hostilities
declared as of noon, December 31, 1946, by presidential proclamation of December 31, 1946
(Proc. no. 2714, 61 Stat. 1048). State of war with the “government of Germany” terminated
October 19, 1951, by Joint Resolution of Congress of that date (65 Stat. 451, ch. 519), by
Presidential Proclamation 2950, October 24, 1951. No peace treaty with Germany was signed.
World War II with Japan
Declared by Joint Resolution of Congress, December 8, 1941 (55 Stat. 795, ch. 561). Japanese
representatives publicly sign unconditional surrender document on the deck of the U.S.S.
Missouri anchored in Tokyo Bay on September 2, 1945. President Truman proclaimed this date
Victory over Japan Day or V-J Day. Cessation of hostilities declared as of 12 noon, December 31,
1946, by presidential proclamation of December 31, 1946 (Proc. no. 2714, 61 Stat. 1048).
Terminated by Multilateral Treaty of Peace with Japan, signed at San Francisco, September 8,
1951 (3 UST 3329), and ratified March 20, 1952, effective April 28, 1952.

May 7, 1945, is listed as V-E day in commentary about signing the first German surrender document in Historic
Documents of World War II by Walter Consuelo Langsam (Westport, CT: Greenwood Press, 1958), p. 144. However,
May 8, 1945, is cited as V-E day in The Encyclopedia of American Facts and Dates, p. 528; as the “Official V-E Day”
in Louis L. Snyder, Louis L. Snyder’s Historical Guide to World War Two (Westport, CT: Greenwood, 1982), p. 736;
and the World Almanac of World War II, ed. Brigadier Peter Young (New York: Pharos Books, 1981), p. 347, states in
its chronology for May 8, “The British and Americans celebrate VE Day (Victory in Europe Day). Truman, Churchill
and King George VI all make special broadcasts.” Although President Truman did not officially proclaim May 7 as VE (Victory in Europe) Day, he did proclaim Sunday, May 13, 1945, a day of prayer. To make for more confusion, his
May 8, 1945, Proclamation 2651, proclaiming May 13 as a day of prayer, is titled, “Victory in Europe; Day of Prayer”
(3 CFR, 1943-1948 Comp.), p. 55. In addition, his May 8 news conference in which he proclaims May 13 a day of
prayer is titled, “The President’s News Conference on V-E Day”—Public Papers of the Presidents of the United States.
Harry S. Truman, 1945 (Washington: GPO, 1961), p. 43.

In his news conference of August 14, 1945, announcing news of the Japanese government’s complete acceptance of
terms of surrender, President Truman states, “Proclamation of V-J Day must wait upon the formal signing of the
surrender terms by Japan.”—Public Papers, p. 216. The proclamation of September 2 as V-J Day was given in his
September 1, 1945, “Speech to the American People after the Signing of the Terms of Unconditional Surrender by
Japan.”—Public Papers, p. 254. However, no formal, numbered proclamation was apparently issued. Both August 14,
the day of President Truman’s announcement of the Japanese surrender, and September 2, the official day proclaimed
by President Truman in his speech, are cited as V-J Day in Chase’s Calendar of Events 2002 (New York: McGrawHill, 2002), pp. 421 and 555. August 15 is cited as V-J Day by The Encyclopedia of American Facts and Dates, 9th ed.,
by Gordon Carruth (New York: Harper Collins, 1993), p. 530. August 15, on which the Japanese Emperor made his
historic broadcast to the Japanese people telling of Japan’s surrender, is cited as V-J Day in The World Almanac of
World War II, p. 353.

ordered U.S. air and sea forces in the Far East to aid South Korea. On June 27, the U.N. Security
Council adopted a resolution asking U.N. members for assistance in repelling the North Korean
armed attack and in restoring peace and security in the area. On June 30, the President stated that
he had authorized the use of certain U.S. air and ground units wherever necessary. No declaration
of war was requested of Congress and no authorization for use of force, by statute, was requested
or enacted. An armistice signed at Panmunjom, Korea, on July 27, 1953, between U.N. and
Communist representatives (4 UST 234; TIAS 2782). No peace treaty was ever signed.

Recent Conflicts: Afghanistan and Iraq
Shortly after the terrorist attacks in the United States on September 11, 2001, President George W.
Bush called on Afghanistan’s leaders to hand over Osama bin Laden and other al Qaeda leaders
and close their terrorist training camps. He also demanded the return of all detained foreign
nationals and the opening of terrorist training sites to inspection.1012 These demands were rejected.
Operation Enduring Freedom (OEF)
Operations began with U.S. military forces deployed on October 7, 2001, and are ongoing in
Afghanistan and in other nations. On March 27, 2009, President Barack Obama announced a new
strategy in Afghanistan and Pakistan and ordered the deployment of 17,000 troops that had been
previously requested by General David McKiernan.11 In President Obama’s “Address to the
Nation on the Way Forward in Afghanistan and Pakistan” at West Point on December 1, 2009, he
stated that “it is in our vital national interest to send an additional 30,000 U.S. troops to
Afghanistan. After 18 months, our troops will begin to come home. These are the resources that
we need to seize the initiative, while building the Afghan capacity that can allow for a responsible
transition of our forces out of Afghanistan.”12
The Administration sought international support from the United Nations (U.N.) for military
action against Afghanistan. U.N. Security Council Resolution 1368 of September 12, 2001, stated
that the Council “Expresses its readiness to take all necessary steps to respond to the terrorist
attacks of September 11, 2001 ... ”13 This resolution was interpreted by many as U.N.
authorization for military action in response to the 9/11 attacks. As a result, Congress passed
S.J.Res. 23, “Authorization for Use of Military Force,” on September 14, 2001. This bill was
signed by President George W. Bush on September 18, 2001, as P.L. 107-40, and it authorized the
President to use “all necessary and appropriate force against those nations, organizations, or
persons he determines planned, authorized, committed, or aided the terrorist attacks that occurred
on September 11, 2001, or harbored such organizations or persons.... ”14 Operations in the region
began with U.S. military forces deployed to the region on October 7, 2001.
Afghanistan—Operation Enduring Freedom
Operations began with U.S. military forces deployed to Afghanistan to combat terrorism on
October 7, 2001, and designated Operation Enduring Freedom (OEF).
On March 27, 2009, President Barack Obama announced a new strategy in Afghanistan and
Pakistan and ordered the deployment of 17,000 troops that had been previously requested by
General David McKiernan.15 In President Obama’s “Address to the Nation on the Way Forward

On June 22, 2011, President Obama again addressed the American people about the way forward
in Afghanistan: “We will begin the drawdown of U.S. troops from a position of strength. We have
exceeded our expectations on our core goal of defeating al-Qaeda killing 20 of its top 30 leaders,
including Osama bin Laden. We have broken the Taliban’s momentum, and trained over 100,000

Afghan National Security Forces.”17 As a result, U.S. forces began the withdrawal of 10,000
troops from Afghanistan.
According to Pentagon Press Secretary George Little on November 26, 2012, Defense Secretary
Leon E. Panetta has yet to forward a recommendation to the White House on how many U.S.
troops should remain in Afghanistan after 2014. He stated: “It’s entirely premature to speculate on
troop numbers in Afghanistan between now and the end of 2014 or beyond. In September [2012],
we completed the full withdrawal of the 33,000 surge troops, and we will soon begin considering
