Why do you think that the bayonet became an old fashioned weapon during World War 1?

Answer 1

Because WWI was about trench warfare, so there was not as much hand-to-hand combat, therefore, the bayonet was not as useful.

Answer 2

The bayonet became an old-fashioned weapon earlier than that, in the American Civil War with the acceptance of the rifle. It could only fire three shots a minute compared to the musket's four, but its range was much longer. Rifles had been in war since the 18th Century, but generals wanted short-ranged muskets with bayonets. When rifles were finally used on a large scale, the musket became obsolete, but the bayonet was retained. Fixed to rifles, bayonets have been used many times in war, but not on the large scale as when they were fixed on the ends of muskets. With a range of only about forty or fifty yards, the bayonet was much more important then. Rifles had a range of two hundred yards or better, and their bayonets seldom got a chance to be used for their intended purpose. * It is often supposed that the machine gun made the bayonet old-fashioned. Actually, most World War 1 casualties were caused by artillery.

Answer 3

Whether it actually is outdated or not is subject to some degree of dispute. Arguments for the obsolescence of bayonets include the capacities of modern military rifles (30+ round magazines versus. the single shot of muzzleloaders), the frequency of urban environments in modern conflicts, and the nature of warfare since the inception of the bayonet, as human wave and bayonet charge tactics are pretty much a thing of the past.
