The development of the bayonet in the late 17th century led to the bayonet charge becoming the main infantry charge tactic through the 18th and 19th centuries and well into the 20th century.
As early as the 19th century, tactical scholars were already noting that most bayonet charges did not result in close combat.
 Instead, one side usually fled before actual bayonet fighting ensued.
The act of fixing bayonets has been held to be primarily connected to morale, the making of a clear signal to friend and foe of a willingness to kill at close quarters.
