Operation Barras was a British Army operation that took place in Sierra Leone on 10 September 2000. The operation aimed to release five British soldiers of the Royal Irish Regiment who had been held by a militia group known as the “West Side Boys”.
The ground operation was conducted by the elite British Special Forces Unit, the 22 Regiment Special Air Service.
The SAS assaulted Gberi Bana in a bid to extract the Royal Irish and elements of 1st Battalion, Parachute Regiment launched a diversionary assault on Magbeni to distract the west side boys for the main objective of hostage rescue.
Operation Barras was one of the most successfully planned and executed tasks the 22 SAS and Paras have completed.
