The earliest battle honour in the British Army is Tangier 1662–80, granted to the Tangier Horse (later known as the 1st Royal Dragoons), the oldest line cavalry regiment of the British army, who in 1969 amalgamated with the Royal Horse Guards to become The Blues and Royals. Also awarded the honour was the 2nd Regiment of Foot, or the Tangier Regiment now The Princess of Wales's Royal Regiment, the senior English regiment in the Union (after the Royal Scots, the senior Scottish and British Regiment), for their protracted 23-year defence of the Colony of Tangier. The battle honour is still held by the successor regiment, the Princess of Wales's Royal Regiment. During these early years of the British standing army, a regiment needed only to engage the enemy with musketry before it was eligible for a battle honour. However, older battle honours are carried on the standards of the Yeomen of the Guard and the Honourable Corps of Gentlemen at Arms, neither of which are part of the army, but are instead the Sovereign's Bodyguard, in the personal service of the sovereign.
