Sir Alan Brooke, in answer to a question by General Marshall, said that the Polish forces consisted (1) of a “secret” army inside Poland and (2) of regular Polish troops outside the country. As regards the first, there was a definite organization of determined men; with leaders, though they were almost entirely unarmed. Their intelligence service had been good, but recently many of their agents had been caught by the Germans and less information about German forces was now coming out from Poland. General Sikorski claimed that by the use of this organization he could do great damage on the Polish railways to interrupt German communications at a critical moment. There could be no doubt that this secret army would play a valuable part in the final rising against Germany, particularly if combined with similar action in adjacent Balkan countries. There was always a danger of a premature rising, however.
The Polish forces outside Poland consisted of an armored division and a parachute brigade with certain other units in the United Kingdom and 2 divisions and 2 brigade groups in the Middle East. General Sikorski’s conception was to get some of these troops into Poland to supplement the secret army. The difficulty was the method of transport, on which General Sikorski was rather vague. He envisaged the use of air transport and parachutes, but there were obvious limitations in this.
General Marshall inquired whether any steps had been taken to meet a request of General Sikorski for the bombing of an area in Poland from which the Germans were clearing out all Polish inhabitants under circumstances of great brutality.
Sir Charles Portal said the Poles had been informed that this operation was impracticable, but steps would be taken to publicize the presence of Polish air forces in the raids on Berlin which might be considered partly as a reprisal on behalf of Poland.
- Raids on Berlin
Sir Charles Portal gave details of the recent raids on Berlin, and estimated that, making all allowance for the comparative sizes of London and Berlin and the time interval, the two raids on Berlin on successive nights had hit Berlin about twice as hard as London had been hit in the two heaviest raids of April and May 1941. The aggregate losses in the two Berlin raids amounted to 6 percent, the figure expected being 10 percent. The effect of the raids would be largely morale though there were important electrical works in the area attacked. They would be a great encouragement to the Russians as well as the Poles.
(Sir Andrew Cunningham entered the meeting at this point.)
- Naval Situation in the Western Mediterranean
Admiral Cunningham said that the Germans might threaten our shipping passing through the Straits of Gibraltar by U-boats and by aircraft and coast defense guns from Southern Spain. He considered the risk from U-boats was comparatively small. The Germans had never been able to maintain many U-boats in the Straits where currents made their operation difficult. The danger from aircraft would be no less than to coastal convoys along the east coast of England. Provided we had fighters established in the airfields of Spanish Morocco, we should be able to deal with this threat. Coast defense guns constituted the greatest danger, but only experience would show how bad this would be. The guns were supposed to have Radar range-finding apparatus but we had means of jamming this which would probably be effective. The guns would have to be neutralized by counter-battery from the southern shore and by air bombardment.
He thought that ships with a speed of 11 knots and upwards would get through the Straits without heavy losses even with the Germans in Southern Spain provided we held Spanish Morocco. Even without it, we should be able to get some convoys through by night. The Planning Staffs at Algiers had been examining the problem and their preliminary conclusions were that if we seized Majorca we should be able to prevent the Germans building up a large air strength in Southern Spain.
Sir Dudley Pound said that in spite of the German coast defense guns on the French shore of the Straits of Dover, we had not lost a ship from them. The range, however, was some 38,000 yards, whereas the distance across the Straits of Gibraltar was only about half that.
Sir Alan Brooke said that a plan had been prepared for seizing Southern Spain with a force of about six divisions. It would not be possible, however, to do this at the same time as Husky. It must be remembered that even if the Spaniards offered no resistance at all it would take some time for the Germans to become fully established in Southern Spain.
Admiral Cunningham, referring to the possibility of capturing Sicily, said that he did not anticipate very heavy shipping losses in the operation but the actual assault of the beaches would be a very expensive operation. He did not consider that the possession of the island would very greatly add to the security of the sea route through the Mediterranean. If we were in Sicily, he would estimate this route as being 90 percent or more secure; without Sicily, it would be about 85 percent secure, once we held the whole of the North African coast.
Sir Charles Portal pointed out that from the air point of view the possession of Sicily would make a very considerable difference. If the Germans were not in the island, it would be difficult for them to operate against our shipping at all; they would have to use bases in Sardinia and the mainland of Italy, which were a considerable distance from the Narrows.
Admiral Cunningham then described the naval situation in the Tunisia area. The Germans had made heavy attacks on Bône on three successive days damaging four merchant ships and a cruiser, but the defenses were now much improved and our cruisers were still operating from the port. We had at first sunk about one ship a day, but the Germans were getting far too many ships into Tunisia now. We should be able to inflict much greater damage on them as soon as we had fully organized our arrangements. Steps were now being taken to block the channel between the Italian minefields with our own mines.
