Armistice. The United States held 48,000. The most dangerous moment was the act of surrender when helpless soldiers were sometimes gunned down. Once prisoners reached a camp, conditions were, in general, satisfactory (and much better than in World WarII), thanks in part to the efforts of the International Red Cross and inspections by neutral nations. However, conditions were terrible in Russia: starvation was common for prisoners and civilians alike; about 15–20% of the prisoners in Russia died, and in Central Powers imprisonment 8% of Russians. In Germany, food was scarce, but only 5% died. The Ottoman Empire often treated POWs poorly. Some 11,800 British Empire soldiers, most of them Indians, became prisoners after the siege of Kut in Mesopotamia in April 1916; 4,250 died in captivity. Although many were in a poor condition when captured, Ottoman officers forced them to march to Anatolia. A survivor said: "We were driven along like beasts; to drop out was to die." The survivors were then forced to build a railway through the Taurus Mountains. In Russia, when the prisoners from the Czechoslovak Legion of the Austro-Hungarian army were released in 1917, they re-armed themselves and briefly became a military and diplomatic force during the Russian Civil War. While the Allied prisoners of the Central Powers were quickly sent home at the end of active hostilities, the same treatment was not granted to Central Power prisoners of the Allies and Russia, many of whom served as forced labour, e.g., in France until 1920. They were released only after many approaches by the Red Cross to the Supreme War Council. German prisoners were still being held in Russia as late as 1924. Military attachés and war correspondents Military and civilian observers from every major power closely followed the course of the war. Many were able to report on events from a perspective somewhat akin to modern "embedded" positions within the opposing land and naval forces. Support for the war In the Balkans, Yugoslav nationalists such as the leader, Ante Trumbić, strongly supported the war, desiring the freedom of Yugoslavs from Austria-Hungary and other foreign powers and the creation of an independent Yugoslavia. The Yugoslav Committee, led by Trumbić, was formed in Paris on 30 April 1915 but shortly moved its office to London. In April 1918, the Rome Congress of Oppressed Nationalities met, including Czechoslovak, Italian, Polish, Transylvanian, and Yugoslav representatives who urged the Allies
