Highland charge

The Highland charge was a battlefield tactic used by the clans of the Scottish Highlands in the 17th and 18th century. It was developed as a response to the evolution of firearms. Previously, Highlanders had fought in tight formations, led by a heavily armoured warrior elite, that carried heavy battle-axes or two handed broadswords known as "claidheamh mor" or "claymores" -meaning "great sword" in Scottish Gaelic. However, with the widespread use of muskets and cannon, such formations became vulnerable. As a result, in the 17th century, Highlanders developed a lighter, one handed claymore with a hilt that protected the hand. This was generally used with a shield or "targe" strapped to the body and a "dirk" or "biotag" (long knife) held in the other hand. The use of the charge greatly mimicked the Celtic fighting styles of battle, where one side would rush at the other in an attempt to break the line of battle.

From the 1640s onwards Highlanders in battle would launch rapid charges, firing their own muskets at close range, before closing with their enemy hand to hand. This became known as the "Highland charge." Its advantage was that it allowed the Highlanders to cover the range of the enemy muskets quickly, before the enemy could inflict many casualties. The Highlanders could then exploit their skills in hand to hand fighting. In this way, they could overwhelm regular troops who were better armed and more conventionally trained.

In practice, the Highland charge proved so effective as much because of its psychological impact as its physical one. Regular troops, when faced with a tide of screaming Highlanders, often lost their heads, fired off an un-aimed volley and began to run away. They would then face the charge not as a disciplined unit, but as a mass of panicked individuals, whom the Highlanders would cut down with impunity. This happened at such battles as Tippermuir and Falkirk. However when, as at the Battle of Culloden in 1746, well trained regular troops kept their composure, the Highland charge was raked with musket volley fire, then faced with an unbroken line of bayonets and beaten off with heavy losses. Cannon firing grapeshot also helped beat off the Highland Charge at Culloden.

The Highland charge was used widely during the Wars of the Three Kingdoms and the Jacobite Risings. The Historian David Stephenson has credited its invention to the Irish warrior Alasdair MacColla, who pioneered its use in Ireland and Scotland during the Wars of the Three Kingdoms. Other historians have questioned this, and suggest that the charge was evolved gradually, to meet a particular set of battlefield challenges. They point out that conventional armies of this era also sometimes used rapid charges with swords, pikes and bayonets when the situation demanded. In the contemporary French army, this was known as an "a prest" attack.
