Instances of Use of United States Armed Forces Abroad, 1798-2009
Congressional Research Service
This report lists hundreds of instances in which the United States has used its armed forces abroad
in situations of military conflict or potential conflict or for other than normal peacetime purposes.
It was compiled in part from various older lists and is intended primarily to provide a rough
survey of past U.S. military ventures abroad, without reference to the magnitude of the given
instance noted. The listing often contains references, especially from 1980 forward, to continuing
military deployments especially U.S. military participation in multinational operations associated
with NATO or the United Nations. Most of these post-1980 instances are summaries based on
Presidential reports to Congress related to the War Powers Resolution. A comprehensive
commentary regarding any of the instances listed is not undertaken here.
The instances differ greatly in number of forces, purpose, extent of hostilities, and legal
authorization. Eleven times in its history the U.S. has formally declared war against foreign
nations. These eleven U.S. war declarations encompassed five separate wars: the war with Great
Britain declared in 1812; the war with Mexico declared in 1846; the war with Spain declared in
1898; the First World War, during which the U.S. declared war with Germany and with Austria-
Hungary during 1917; and World War II, during which the U.S. declared war against Japan,
Germany, and Italy in 1941, and against Bulgaria, Hungary, and Rumania in 1942.
Some of the instances were extended military engagements that might be considered undeclared
wars. These include the Undeclared Naval War with France from 1798 to 1800; the First Barbary
War from 1801 to 1805; the Second Barbary War of 1815; the Korean War of 1950-1953; the
Vietnam War from 1964 to 1973; the Persian Gulf War of 1991; global actions against foreign
terrorists after the September 11, 2001, attacks on the United States; and the war with Iraq in
2003. With the exception of the Korean War, all of these conflicts received Congressional
authorization in some form short of a formal declaration of war. Other, more recent instances
often involve deployment of U.S. military forces as part of a multinational operation associated
with NATO or the United Nations.
The majority of the instances listed prior to World War II were brief Marine or Navy actions to
protect U.S. citizens or promote U.S. interests. A number were actions against pirates or bandits.
Covert actions, disaster relief, and routine alliance stationing and training exercises are not
included here, nor are the Civil and Revolutionary Wars and the continual use of U.S. military
units in the exploration, settlement, and pacification of the western part of the United States. This
report will be updated as warranted.

Congressional Research Service 1
The following list reviews hundreds of instances in which the United States has utilized military
forces abroad in situations of military conflict or potential conflict to protect U.S. citizens or
promote U.S. interests. The list does not include covert actions or numerous instances in which
U.S. forces have been stationed abroad since World War II in occupation forces or for
participation in mutual security organizations, base agreements, or routine military assistance or
training operations. Because of differing judgments over the actions to be included, other lists
may include more or fewer instances.1
The instances vary greatly in size of operation, legal authorization, and significance. The number
of troops involved range from a few sailors or Marines landed to protect American lives and
property to hundreds of thousands in Korea and Vietnam and millions in World War II. Some
actions were of short duration and some lasted a number of years. In some instances a military
officer acted without authorization; some actions were conducted solely under the President’s
powers as Chief Executive or Commander in Chief; other instances were authorized by Congress
in some fashion. In eleven separate cases (listed in bold-face type) the United States formally
declared war against foreign nations. For most of the instances listed, however, the status of the
action under domestic or international law has not been addressed. Most instances listed since
1980, are summaries of U.S. military deployments reported to Congress by the President as a
result of the War Powers Resolution. Several of these Presidential reports are summaries of
activities related to an on-going operation previously reported. It is important to note that
inclusion in this list does not connote either legality or level of significance of the instance
described. This report covers uses of U.S. military force abroad from 1798 through mid-
December 2009. It will be revised as circumstances warrant.

1798-1800 Undeclared Naval War with France. This contest included land actions, such as that in
the Dominican Republic, city of Puerto Plata, where marines captured a French
privateer under the guns of the forts. Congress authorized military action through a
series of statutes.

authorized U.S. military action by statute.
