Operation Collar and The action off Cape Spartiavento (Sardinia)

Operation Collar (24-30 November 1940) was a British naval operation launched from both ends of the Mediterranean, with the intention of combining the movement of two small convoys with the redistribution of British naval forces.
The action off Cape Spartiavento (Sardinia) of 27 November 1940 was an inconclusive clash between elements of the British and Italian fleets which came about because of Italian efforts to interfere with Operation Collar.
