Bayonets in the Civil War
Bayonets in the Civil War were among the most common weapons attached to rifles. Used as a weapon for close contact, the bayonets of the Civil War era may be responsible for the most deaths of any weapon of the era. Because rifles at this time were hard to reload and were often inaccurate, many soldiers used the bayonet as their #1 weapon.
By the time of World War I the bayonet was still a prominent weapon but used less and less in actual combat, as the rifles of the time period were more powerful and accurate. The Civil War era bayonets were the last time period where this weapon became the most powerful fighting weapon of a war.
