I want my "S" Branch to make a chart of all the thirty divisions, showing their progress towards complete equipment. Each division would be represented by a square divided into sections: officers and men, rifles, Bren guns, Bren-gun carriers, anti-tank rifles, ant.i.tank guns, field artillery, medium ditto (if any), transport sufficient to secure mobility of all three brigades simultaneously, etc. As and when a proportion of these subsidiary squares is completed, a chart can be painted red. I should like to see this chart every week. A similar diagram can be prepared for the Home Guard. In this case it is only necessary to show rifles and uniforms.

Prime Minister to Secretary of State for War.

You shared my astonishment yesterday at the statement made to us by General McNaughton that the whole of the 2d Canadian Division was destined for Iceland. It would surely be a very great mistake to allow these fine troops to be employed in so distant a theatre. Apparently the first three battalions have already gone there. No one was told anything about this. We require two Canadian divisions to work as a corps as soon as possible.I am well aware of the arguments about training, etc., but they did not convince me. We ought to have another thorough re-examination of this point. Surely it should be possible to send second-line Territorial troops to Iceland, where they should fortify themselves at the key points, and then to have, say, one very high-cla.s.s battalion of the "Gubbins" type in order to strike at any landing. I should be most grateful if you would deal with this.

Prime Minister to First Lord and First Sea Lord.

1. I cannot understand how we can tolerate the movement at sea along the French coast of any vessels without attacking them. It is not sufficient surely to use the air only. Destroyers should be sent under air escort. Are we really to resign ourselves to the Germans building up a large armada under our noses in the Channel, and conducting vessels through the Straits of Dover with impunity? This is the beginning of a new and very dangerous threat which must be countered.2. I should be glad of a report not only on the points mentioned above, but also on the state of our minefield there, and how it is to be improved. Is it true the mines have become defective after ten months? If so, several new rows should be laid. Why should not an effort be made to lay a minefield by night in the French pa.s.sage, and lie in wait for any craft sent to sweep a channel through it? We really must not be put off from a.s.serting our sea power by the fact that the Germans are holding the French coast. If German guns open upon us, a heavy ship should be sent to bombard them under proper air protection.

During this month of July, American weapons in considerable quant.i.ties were safely brought across the Atlantic. This seemed to me so vital that I issued reiterated injunctions for care in their transportation and reception.

Prime Minister to Secretary of State for War.

7.VII.40.

I have asked the Admiralty to make very special arrangements for bringing in your rifle convoys. They are sending four destroyers far out to meet them, and all should arrive during the 9th. You can ascertain the hour from the Admiralty. I was so glad to hear that you were making all preparations for the unloading, reception, and distribution of these rifles. At least one hundred thousand ought to reach the troops that very night, or in the small hours of the following morning. Special trains should be used to distribute them and the ammunition according to a plan worked out beforehand exactly, and directed from the landing-port by some high officer thoroughly acquainted with it. It would seem likely that you would emphasise early distribution to the coastal districts, so that all the Home Guard in the danger areas should be the first served. Perhaps you would be good enough to let me know beforehand what you decide.

Prime Minister to General Ismay.

8.VII.40.

Have any steps been taken to load the later portions of American ammunition, rifles, and guns upon faster ships than was the case last time? What are the ships in which the latest consignments are being packed, and what are their speeds? Will you kindly ascertain this from the Admiralty.

Prime Minister to First Lord.

27.VII.40.

The great consignments of rifles and guns, together with their ammunition, which are now approaching this country are entirely on a different level from anything else we have transported across the ocean except the Canadian Division itself. Do not forget that two hundred thousand rifles mean two hundred thousand men, as the men are waiting for the rifles. The convoys approaching on July 31 are unique, and a special effort should be made to ensure their safe arrival. The loss of these rifles and field guns would be a disaster of the first order.

When the ships from America approached our sh.o.r.es with their priceless arms, special trains were waiting in all the ports to receive their cargoes. The Home Guard in every county, in every town, in every village, sat up all through the nights to receive them. Men and women worked night and day making them fit for use. By the end of July we were an armed nation, so far as parachute or air-borne landings were concerned. We had become a "hornet's nest." Anyhow, if we had to go down fighting (which I did not antic.i.p.ate), a lot of our men and some women had weapons in their hands. The arrival of the first instalment of the half-million .300 rifles for the Home Guard (albeit with only about fifty cartridges apiece, of which we dared only issue ten, and no factories yet set in motion) enabled us to transfer three hundred thousand .303 British-type rifles to the rapidly expanding formations of the Regular Army.

At the seventy-fives, with their thousand rounds apiece, some fastidious experts presently turned their noses up. There were no limbers and no immediate means of procuring more ammunition. Mixed calibres complicate operations. But I would have none of this, and during all 1940 and 1941 these nine hundred seventy-fives were a great addition to our military strength for Home Defence. Arrangements were devised and men were drilled to run them up on planks into lorries for movement. When you are fighting for existence, any cannon is better than no cannon at all, and the French seventy-five, although outdated by the British twenty-five-pounder and the German field gun-howitzer, was still a splendid weapon.

We had watched with attention the growth of the German heavy batteries along the Channel coast during August and September. By far the strongest concentration of this artillery was around Calais and Cape Gris-Nez, with the apparent purpose not only of forbidding the Straits to our warships, but also of commanding the shortest route across them. We now know that by the middle of September the following batteries were already mounted and ready for use in this region alone: (a) Siegfried battery, south of Gris-Nez, with four 38-cm. guns. Siegfried battery, south of Gris-Nez, with four 38-cm. guns.(b) Friedrich-August battery, north of Boulogne, with three 30.5-cm. guns. Friedrich-August battery, north of Boulogne, with three 30.5-cm. guns.(c) Grosser Kurfuerst battery, at Gris-Nez, with four 28-cm. guns. Grosser Kurfuerst battery, at Gris-Nez, with four 28-cm. guns.(d) Prinz Heinrich battery, between Calais and Blanc-Ncz, with two 28-cm. guns. Prinz Heinrich battery, between Calais and Blanc-Ncz, with two 28-cm. guns.(e) Oldenburg battery, east of Calais, with two 24-cm. guns. Oldenburg battery, east of Calais, with two 24-cm. guns.(f) M.1, M.2, M.3, M.4 batteries, in the sector of Gris-Nez Calais, with a total of 14 17-cm. guns. M.1, M.2, M.3, M.4 batteries, in the sector of Gris-Nez Calais, with a total of 14 17-cm. guns.

Besides this, no fewer than thirty-five heavy and medium batteries of the German Army, as well as seven batteries of captured guns, were sited along the French coast for defensive purposes by the end of August.

The orders which I had given in June for arming the Dover promontory with guns that could fire across the Channel had borne fruit, though not on the same scale. I took a personal interest in the whole of this business. I visited Dover several times in these anxious summer months. In the citadel of the castle large underground galleries and chambers had been cut in the chalk, and there was a wide balcony from which on clear days the sh.o.r.es of France, now in the hands of the enemy, could be seen. Admiral Ramsay, who commanded, was a friend of mine. He was the son of a colonel of the 4th Hussars under whom I had served in my youth, and I had often seen him as a child on the Barrack Square at Aldershot. When three years before the war he had resigned his position as Chief of the Staff to the Home Fleet through a difference with its Commander-in-Chief, it was to me that he had come to seek advice. I had long talks with him, and together with the Dover Fortress Commander visited our rapidly improving defences.

I carefully studied there and at home the Intelligence reports, which almost daily showed the progress of the German batteries. The series of Minutes which I dictated about the Dover guns during August show my very great desire to break up some of the heaviest battery-sites before their guns could reply. I certainly thought this ought to have been done in August, as we had at least three of the very heaviest guns capable of firing across the Channel. Later on the Germans became too strong for us to court a duel.

Prime Minister to General Ismay.

1. The fourteen-inch gun I ordered to be mounted at Dover should be ready in ample time to deal with this new German battery. It certainly should not fire until all the guns are in position. The plan for the shoot may, however, now be made, and I should like to know what arrangements for spotting aircraft, protected by Fighters in strength, will be prepared for that joyous occasion. Also, when the two guns, 13.5's on railway mountings, will be ready, and whether they can reach the target mentioned. Several other camouflaged guns should be put up at various points, with arrangements to make suitable flashes, smoke, and dust. Let me know what arrangements can be devised. I presume work on the railway extensions for the 13.5's is already in hand. Please report.2. The movement of the German warships southward to Kiel creates a somewhat different situation from that dealt with in C.-in-C. Home Fleet's appreciation asked for some time ago about an invasion across the narrow waters supported by heavy ships. The Admiralty should be asked whether C.-in-C.'s attention should not be drawn to the altered dispositions of the enemy, in case he has anything further to say.

Prime Minister to First Lord.

8.VIII.40.

I am impressed by the speed and efficiency with which the emplacement for the fourteen-inch gun at Dover has been prepared and the gun itself mounted. Will you tell all those who have helped in this achievement how much I appreciate the sterling effort they have made.The enemy batteries first opened fire on August 22, engaging a convoy without effect and later firing on Dover. They were replied to by one of our fourteen-inch guns which was now in action. Thenceforward there were artillery duels at irregular intervals. Dover was engaged six times in September, the heaviest day being September 9, when over a hundred and fifty sh.e.l.ls were fired. Very little damage was done to convoys.

Prime Minister to First Lord and First Sea Lord.

25.VIII.40.

I shall be much obliged if you will make proposals for a shoot by Erebus Erebus 6 6 against the German batteries at Gris-Nez. I was very glad to hear you thought this practicable. It is most desirable. There is no reason why it should wait for the railway guns, though, of course, if they were ready they could follow on with the fourteen-inch at daybreak. We ought to smash these batteries. I hope we have not got to wait for the next moon for against the German batteries at Gris-Nez. I was very glad to hear you thought this practicable.

It would not seem unreasonable that the enemy should attempt gradually to master the Dover promontory and command the Channel at its narrowest point. This would be a natural preliminary to invasion. It would give occasion for continued fighting with our Air Force in the hope of exhausting them by numbers. It would tend to drive our warships from all the Channel bases. The concentration of many batteries on the French coast must be expected. What are we doing in defence of the Dover promontory by heavy artillery? Ten weeks ago I asked for heavy guns. One has been mounted. Two railway guns are expected. Now we are told these will be very inaccurate on account of super-charging. We ought to have a good many more heavy guns lined up inside to smaller calibre with stiffer rifling and a range of at least fifty miles, and firing at twenty-five or thirty miles would then become more accurate. I do not understand why I have not yet received proposals on this subject. We must insist upon maintaining superior artillery positions on the Dover promontory, no matter what form of attack they are exposed to. We have to fight for the command of the Straits by artillery, to destroy the enemy's batteries, and to multiply and fortify our own.I have sent on other papers a request for a surprise attack by Erebus, Erebus, which should be able to destroy the batteries at Gris-Nez. She has an armoured deck against air-bombing. What is being done about this? When is she going into action? The Air Ministry should, of course, co-operate. The operation would take an offensive turn. We should require spotting aircraft by day. It may be that the first squadrons of Hurricanes fitted with Merlin 20 would be the best for this.

Further to my previous Minute on defence of the Kentish promontory, we must expect that very powerful batteries in great numbers will be rapidly brought into being on the French coast. It would be a natural thought for the Germans to try to dominate the Straits by artillery. At present we are ahead of them with our fourteen-inch and two 13.5 railway guns. The Admiral at Dover should be furnished in addition, as soon as possible, with a large number of the most modern six-inch or eight-inch guns. I understand the Admiralty is considering taking guns from [H.M.S.] Newcastle Newcastle or or Glasgow, Glasgow, which are under long repair. A record evolution should be made of getting one or two of these turrets mounted. Report to me about this and dates. There is a 9.2 Army experimental gun and mounting, and surely we have some twelve-inch on railway mountings. If our ships cannot use the Straits, the enemy must not be able to. Even if guns cannot fire onto the French sh.o.r.e, they are none the less very valuable. which are under long repair. A record evolution should be made of getting one or two of these turrets mounted.

If our ships cannot use the Straits, the enemy must not be able to. Even if guns cannot fire onto the French sh.o.r.e, they are none the less very valuable.Some of our heavy artillery the eighteen-inch howitzer and the 9.2's should be planted in positions whence they could deny the ports and landings to the enemy, and as C.I.G.S. mentioned, support the counter-attack which would be launched against any attempted bridgehead. Much of this ma.s.s of artillery I saved from the last war has done nothing, and has been under reconditioning for a whole year.Let me have a good programme for using it to support counter-strokes and deny landings, both north and south of the Thames. Farther north I have seen already some very good heavy batteries.I should like also to be informed of the real [actual] lines of defence drawn up between Dover and London and Harwich and London. Now that the coast is finished, there is no reason why we should not develop these lines, which in no way detract from the principle of vehement counter-attack.But the most urgent matter is one or two modern six-inch to shoot all German craft up to thirty-five thousand yards.I am also endeavouring to obtain from United States at least a pair of their sixteen-inch coast-defence weapons. These fire forty-five thousand yards, throwing a ton and a quarter, without being super-charged. They should therefore be very accurate. General Strong, United States Army, mentioned this to me as a promising line. He thought, without committing his Government, that the United States Army might be prepared to take a couple of these guns and their carriages away from some of their twin batteries.Let me know all details about these guns. It ought to be possible to make the concrete foundation in three months, and I expect it would take as long to get these guns over here. There are very few ships that can carry them on their decks.

Prime Minister to General Ismay and First Sea Lord.

31.VIII.40.

It becomes particularly urgent to attack the batteries on the French sh.o.r.e. Yesterday's photographs show guns being actually hoisted up into position, and it will be wise to fire on them before they are able to reply. There are quite enough guns in position already. I trust, therefore, Erebus Erebus will not be delayed, as every day our task will become harder. will not be delayed, as every day our task will become harder.It seems most necessary to damage and delay the development of the hostile batteries in view of the fact that we are so far behindhand with our own.
