Each soldier in the Union Army was issued a canvas shelter half. When two soldiers buttoned their shelter halves together, it became a “dog tent”. This was the soldier’s primary shelter while on campaign during Spring, Summer, and Fall. Each soldier carried their shelter half in their knapsack. The Confederate soldier was not as fortunate at times when it came to being issued a tent or shelter half. Due to scarce resources, the Confederate soldier, at times, had to use captured Union tents or just did without and slept with a blanket under the stars.
