Johnston's Army refers to the military forces led by General Joseph E. Johnston during the American Civil War. This army was primarily active in the Confederate States and played a significant role in various battles, including the Battle of Bull Run and the Atlanta Campaign. Johnston was known for his strategic defensive tactics and his ability to retreat effectively to preserve his forces. The army faced numerous challenges, including supply shortages and the overwhelming numbers of Union forces. Despite these difficulties, Johnston's leadership was marked by his efforts to maintain troop morale and cohesion. Ultimately, Johnston's Army was involved in key engagements until the end of the war in 1865.
