Why do think that the bayonet became an old fashioned weapon during this war?

The bayonet became an old-fashioned weapon during the war due to the rise of modern firearms and advancements in military tactics. As armies increasingly relied on rapid-fire rifles and automatic weapons, the need for close-quarters combat diminished. Additionally, the introduction of trench warfare made traditional charges with bayonets less effective and more dangerous, leading to a shift toward more strategic and ranged combat techniques. Consequently, the bayonet's role in warfare was reduced, marking it as an outdated weapon in the context of modern combat.
