A soldier's home in camp was a rectangular piece of canvas buttoned to another to form a small two-man tent or dog tent as the soldiers called them. First introduced in 1862, every Union soldier was issued one for use during active campaign and the men joked that only a dog could crawl under it and stay dry from the rain. The tent could be easily pitched for the evening by tying each end to a rifle stuck in the ground by the bayonet or by stringing it up to fence rails. Confederates did not receive shelter tents though some Confederate units were issued a variation of the tent, which they pitched as a lean-to or shelter. As the war progressed it was very common for a Confederate camp to be filled with captured Union tents as well as captured blankets, canteens, and haversacks. Confederates especially prized the Union rubber blankets, which were not manufactured in the south and were ideal as a ground cloth or overhead shelter.
