Operation Acid Drop was a British Commando raid during World War II. This was the first commando raid carried out by No. 5 Commando and consisted of two simultaneous operations over the night of 30/31 August 1941. Each raid consisted of one officer and 14 men, their targets were the beaches at Neufchâtel-Hardelot and Merlimont in the Pas-de-Calais, France with the aim of carrying out reconnaissance and if possible, to capture a German soldier. It was a hit and run type raid with only 30 minutes ashore but in the event neither party encountered any Germans.[1][2]
