What Is the Black Watch? | A Highland Regiment’s History

When you search for the Black Watch, you’re likely looking for the historic Scottish infantry regiment of the British Army, a name that carries centuries of military history. The term, however, can point to three related things: the original British regiment, a separate Canadian regiment, or the distinctive dark tartan pattern. Understanding which one you mean is the first step, and knowing the regiment’s story explains why the name endures.

The Origins of the Name

The name “Black Watch” is tied to both the regiment’s dark uniform and its original duty. Britannica attributes the name to the regiment’s sombre tartan, contrasting it with the red-coated regular troops of the era. The National Army Museum adds that the unit was commonly called Am Freiceadan Dubh, Gaelic for “the dark watch,” a reference to its dark green government-issue tartan.

The regiment’s role also shaped its identity. Raised to police the Highlands after the 1715 Jacobite Rebellion, these men were literally a “watch” over the region. The Scots Language Dictionary confirms this dual meaning, noting the name comes from both the dark colors and the unit’s policing duties.

Formation and Key Dates

The Black Watch began as six independent Highland companies raised in 1725 to keep peace in the Highlands. These were amalgamated into the 43rd Regiment of Foot in September 1739, later becoming the 42nd Highland Regiment of Foot in 1751. The regiment received the “Royal” title in 1758, becoming the Black Watch (Royal Highland Regiment).

This lineage has led to some confusion over dates. Sources differ on whether to mark the origin from the 1725 companies, the 1739 amalgamation, or later redesignations. The safest framing is to note the independent companies came first, with the formal regiment following in 1739.

A History of Service

The Black Watch saw its first action against the French at the First Battle of Fontenoy in 1745. Over the following centuries, the regiment fought at Long Island (1776), in Egypt and Spain during the Napoleonic Wars, in the Crimean War (1854–1856), the Indian Mutiny (1857–1859), the Boer War (1899–1902), and both world wars. More recently, the Black Watch was the final garrison unit in Hong Kong in 1997 before the handover to China.

The regiment existed until 28 March 2006, when it was merged into the Royal Regiment of Scotland. Its modern successor is the 3rd Battalion, The Royal Regiment of Scotland (3 SCOTS).

The Tartan and the Canadian Regiment

The Black Watch tartan is a dark pattern of blue, green, and black. The National Army Museum notes the regiment wore kilts as part of its everyday uniform until 1940. Today, the tartan is widely treated as an open tartan, not exclusive to any clan, though this is a modern interpretation rather than a strict historical rule.

Separately, the Black Watch (Royal Highland Regiment) of Canada is a distinct unit. Veterans Affairs Canada describes it as the oldest highland regiment in Canada. Raised in Montreal on 31 January 1862 as the 5th Battalion, Volunteer Militia Rifles of Canada, it was formed for border service due to tensions with the United States during the American Civil War. The Canadian regiment saw combat at Dieppe on 19 August 1942 and later fought across North Western Europe in World War II.

A common mistake is treating the Canadian Black Watch as the same unit as the British one; they are separate regiments with distinct lineages. Another is assuming the term refers to a US military unit—it does not. The name belongs to the Scottish, British, and Canadian highland traditions.
