The Union Army was the name given to the United States Army during the American Civil War when it fought to preserve the Union of states. The Union Army was also known as the Federal Army or the Northern Army.
The Union Army was made up of several armies, including the Army of the Potomac, the Army of the Ohio, the Army of the Cumberland, and the Army of the Tennessee. These armies were named after the main bodies of water in their regions. The Union Army was made up of both regular U.S. soldiers and volunteer units from the Northern and Western states.
The Union Army was victorious over the Confederate Army in 1865. The Union's success was due to a number of factors, including:
Industrial resources: The Northeast and Midwest provided the resources to produce munitions and supplies, and to finance the war.
Soldiers: The Union had soldiers from the Northern and Western states.
Support: Most Northern states had Republican governors who supported the war effort.
The Union Army's soldiers wore blue uniforms, which included a blue forage cap, dark blue sack coat, blue wool trousers, and leather brogans. They carried a knapsack that contained a tent, groundsheet, overcoat, and personal belongings.
