In David Thomas's The importance of Commando Operations in Modern Warfare 1939-82 he states: "Commando operations in the sense of self-contained acts of war mounted by forces operating within enemy territory are as old as warfare itself. However, before the second world war, the types of missions that later would become known as 'commando operations', were regarded in western military thought as belonging to the separate phenomenon of irregular warfare, that is, to partisan and guerrilla activity. Therefore, the several [British Commando] forces which came into existence between 1940 and 1942 owed their formation not to British army strategy and doctrine, nor to any far-reaching conception of commando warfare, but to the fertile imagination of Prime Minister Churchill and a number of gifted officers."
