Facing the German 7th Army to the west were the U.S. VIII Corps (of the 9th Army), V Corps, and XII Corps (both of the 3rd Army). VIII Corps numbered one armored and three infantry divisions while V Corps was made up of one armored division and two infantry divisions. An additional infantry division under control of 3rd Army Headquarters was also in V Corps' sector, and a second armored division would be subordinated to V Corps before VE Day. XII Corps commanded two armored divisions and two infantry divisions. Exerting some pressure on German 7th Army, these corps of the U.S. Army did not advance on Prague although their presence in western Bohemia stimulated Czech resistance to the German occupation, indirectly influencing the Prague uprising. By agreement with the Soviets, the U.S. forces did not advance in strength eastward of an irregular demarcation line that at points touched Leipzig, Karlovy Vary, and Plzen.
