Operation Nicety was an operation in September 1942 during the Second World War by the Sudan Defence Force. It was designed to support the raiding forces taking part in Operation Agreement, Operation Caravan and Operation Brevity. The objective of the operation was the seizure of the Jalo oasis in the Libyan desert, to support the withdrawal of the forces involved in the other operations. The operation was a failure: the Germans had discovered the plans for all four operations on the body of a dead officer taking part in Operation Agreement. Forewarned, the garrison at Jalo had been warned and reinforced which easily repelled the attack on the night 15–16 September.
