'Windscreen' was a British sequence of three plans, modified as the situation changed, to edge Generalfeldmarschall Erwin Rommel’s Deutsch-Italienische Panzerarmee out of its defensive positions at El Agheila and Buerat as General Sir Bernard Montgomery’s British 8^th Army undertook its 'Guillotine' (ii) advance after the 2^nd Battle of El Alamein (January 1943).

The plan, drafted by Colonel Dudley W. Clarke’s 'A' Force deception apparatus, was based on the use of 'special means' (double agents) to indicate that the British were planning an amphibious landing to take Tripoli, well to the rear of the Axis forces' current positions, in order to cut the German and Italian forces' lines of communication and retreat.
