Union soldiers were members of the Union Army, the military force that fought for the northern states during the American Civil War from 1861 to 1865. They were primarily tasked with preserving the United States and ending the institution of slavery. Soldiers came from various backgrounds, including farmers, laborers, and immigrants, and they served in different roles, such as infantry, cavalry, and artillery. These soldiers faced numerous challenges, including harsh weather, limited supplies, and the threat of battle. Many fought in significant battles, such as Gettysburg and Antietam, and their efforts ultimately contributed to the Union's victory. After the war, many Union soldiers returned home, while others continued to serve in various capacities, helping to shape the nation’s future.
