A prize of war is a piece of enemy property or land seized by a belligerent party during or after a war or battle, typically at sea. This term was used nearly exclusively in terms of captured ships during the 18th and 19th centuries. Basis in international law Rules defining how prizes were claimed and administered originated before there were organized government navies and were an outgrowth of privateering. Current international treaties provide for the retention of personal property by captured soldiers as well as issues of personal equipment in their possession when captured (including clothing, helmets, rank insignia and medals, and protective equipment such as gas masks), but excluding certain issue items such as weapons, horses, maps, and military documents. Non-personal equipment, vehicles, artillery pieces, ships, stockpiles of food and other material belongs to the capturing state and it may be used without any restriction. Notable prize-takings The 28th Virginia battle flag, from the American Civil War, is a Confederate battle flag that belonged to the 28th Virginia Infantry Regiment. Captured by the 1st Minnesota Infantry Regiment at the Battle of Gettysburg, the flag was brought to Minnesota and exhibited at the state's capitol for several years before passing into the permanent collection of the Minnesota Historical Society after 1896 where it has remained since. Although various groups in Virginia have requested that the flag be returned, beginning as early as 1960, Minnesota has repeatedly declined to return it, with Governor Jesse Ventura asking "Why? I mean, we won." Prizes in World War II included a German submarine later called , and which was captured by elements of the United States Navy in a task force commanded by then-Captain Daniel V.

Although not taken in combat, three -class barques were confiscated from Germany as reparation prizes at the conclusion of World War II, one of which remains in US service as .
