The American Civic War (1861-1865) was fought between the United States of America (USA), called the Union during this war, and the Confederate States of America (CSA), commonly known as Confederation. The main cause of the outbreak of the war, among many others, also of considerable importance, was the announcement of the Confederation's secession (secession) from the Union. Of course, both in the North and in the South, when the war broke out, the army began to be built. In the case of the Union's army, the main type of armed force - when it comes to numbers - was the infantry. The infantry was formed into regiments that were divided into companies. The full-time US infantry regiments had 700-1000 men, especially at the beginning of the war, but in practice the force of the regiments was from 300 to 400 men. It is worth adding that the regiments were formed into brigades with the strength of about 1500-2000 people, and those into divisions. The basic weapon of a US infantry at that time was a rifle with a rifled barrel, often made by Spencer, with a caliber of 14.73 mm and an effective range of up to 500 meters. On top of that, of course, was the bayonet. It is worth adding that the Union's infantry was perceived as inferior to its Confederate counterpart. It often gave way to its morale and will to fight - especially in the initial period of a conflict. Often, especially at the division or corps level, it was also less well-commanded. On the other hand, it was better equipped, often also better nourished, and often outnumbered the enemy. With time, also, especially after 1863, the qualitative difference began to blur very much. It is worth adding that during the entire Civil War, the Union mobilized approx. 2.1 million people for arms, of which approx. 350-400 thousand. people died, and you can also find data that over 500,000 died. Union soldiers.
