ABSTRACT
On 26 July 1939, a Major of the Polish Intelligence Corps addressed a group of British Military Intelligence officers assembled in the resident clerk's office, next to room 427 of the War Office, in London. The subject of his talk was plans for guerrilla-style warfare to be carried out should the Germans invade and overrun Poland. Late in August, a Military Mission, the Number 4 Military Mission, was despatched to Poland by the British Government to carry out two tasks. The first of these was to keep the War Office in London ‘fully and continuously’ informed of the military situation, and the second was to ensure a continuation programme for cooperation by the Polish Army in the combined plan of the Allies. Added to the brief was a note urging the Mission, in view of the difficulties involved in supplying direct support to the Poles, to do everything, as a matter of the greatest importance, to inspire confidence. 1
