1964 1965 1967 The Battle of Crater or Operation Stirling Castle was an encounter in 1967 during the Aden Emergency.

[1] The operation began on 3 July 1967 with the Argyll and Sutherland Highlanders commanded by Lt-Col Colin Mitchell ("Mad Mitch") performing a night invasion of Crater, which he termed Operation Stirling Castle, after the Argylls’ regimental headquarters.

The enemy was taken totally by surprise, and effective resistance ceased.

[2][3][4] A particular sign of Mitchell’s confidence was his decision to order the pipe band to march down the main street of Crater, playing regimental tunes, for which the Pipe major was mentioned in despatches.

[5] British troops remained in Crater until the end of the Emergency.
