Before the adoption of ring attachments for bayonets, the attachment consisted of a plug inserted into the barrel, which meant a musket could not be fired or reloaded with a fixed bayonet. During their charge Highlanders made a relatively instant transition from firearms to swords as they swiftly closed with the opposing force. Those enemy soldiers with plug attachments (some carried a pike) had only moments to fix bayonets while under psychological pressure from the onrushing Highlanders brandishing swords and roaring their war cries. At the Battle of Killiecrankie Lowland Scots who were veterans of the Dutch wars were overwhelmed by Highlanders of clan Cameron; the Highlanders secured a complete victory by a charge which killed 2000 redcoats for the loss of 800 Highlanders.
