When I had had the first tank made twenty-five years before, I turned to Tennyson d"Eyncourt, Director of Naval Construction, to solve the problem. Accordingly I broached the subject in November to Sir Stanley Goodall, who now held this most important office, and one of his ablest a.s.sistants, Mr. Hopkins, was put in charge with a grant of one hundred thousand pounds for experiments. The design and manufacture of a working model was completed in six weeks by Messrs. Ruston-Bucyrus of Lincoln. This suggestive little machine, about three feet long, performed excellently in the Admiralty bas.e.m.e.nt on a floor of sand. Having obtained the active support of the Chief of the Imperial General Staff, General Ironside, and other British military experts, I invited the Prime Minister and several of his colleagues to a demonstration. Later I took it over to France and exhibited it both to General Gamelin and later on to General Georges, who expressed approving interest. On December 6, I was a.s.sured that immediate orders and absolute priority would produce two hundred of these machines by March, 1941. At the same time it was suggested that a bigger machine might dig a trench wide enough for tanks.
On February 7, 1940, Cabinet and Treasury approval were given for the construction of two hundred narrow "infantry" and forty wide "officer" machines. The design was so novel that trial units of the main components had first to be built. In April, a hitch occurred. We had hitherto relied on a single Merlin-Marine type of engine, but now the Air Ministry wanted all these, and another heavier and larger engine had to be accepted instead. The machine in its final form weighed over a hundred tons, was seventy-seven feet long, and eight feet high. This mammoth mole could cut in loam a trench five feet deep and seven-and-a-half feet wide at half-a-mile an hour, involving the movement of eight thousand tons of soil. In March, 1940, the whole process of manufacture was transferred to a special department of the Ministry of Supply. The utmost secrecy was maintained by the three hundred and fifty firms involved in making the separate parts, or in a.s.sembling them at selected centres. Geological a.n.a.lysis was made of the soil of Northern France and Belgium, and several suitable areas were found where the machine could be used as part of a great offensive battle plan.
But all this labour, requiring at every stage so many people to be convinced or persuaded, led to nothing. A very different form of warfare was soon to descend upon us like an avalanche, sweeping all before it. As will presently be seen, I lost no time in casting aside these elaborate plans and releasing the resources they involved. A few specimens alone were finished and preserved for some special tactical problem or for cutting emergency anti-tank obstacles. By May, 1943, we had only the pilot model, four narrow and five wide machines, made or making. After seeing the full-sized pilot model perform with astonishing efficiency, I minuted "cancel and wind up the four of the five "officer" type, but keep the four "infantry"-type in good order. Their turn may come." These survivors were kept in store until the summer of 1945, when the Siegfried Line being pierced by other methods, all except one was dismantled. Such was the tale of "Cultivator Number 6." I am responsible but impenitent.

OPERATION "ROYAL MARINE"
Note by the First Lord of the Admiralty.
March 4, 1940. 4, 1940.
1. It will be possible to begin the naval operation at any time at twenty-four hours" notice after March 12. At that time there will, as planned, be available two thousand fluvial mines of the naval type, comprising three variants. Thereafter a regular minimum supply of one thousand per week has been arranged. The detachment of British sailors is on the spot, and the material is ready. All local arrangements have been made with the French through General Gamelin and Admiral Darlan. These mines will, it is believed, affect the river for the first hundred miles below Karlsruhe. There is always risk in keeping men and peculiar material teed-up so close (four to six miles) to the enemy"s front, although within the Maginot Line. The river is reported to be in perfect order this month. It will probably be deepened by the melting of the snows in April, involving some lengthening of the mine-tails; also the flow from the tributaries may be temporarily stopped or even reversed.2. The air force will not be ready till the moon is again good in mid-April. Therefore, unless our hand is forced by events, it would seem better to wait till then, so as to infest the whole river simultaneously, and thus also confuse the points of naval departure. By mid-April the air force should have a good supply of mines which could be laid every night during the moon in the reaches between Bingen and Coblentz. All mines of both cla.s.ses will become harmless before reaching the Dutch frontier. Before the end of April it is hoped that a supply of the special mines for the still-water ca.n.a.ls may be ready, and by the May moon the mines for the mouths of rivers flowing into the Heligoland Bight should be at hand.3. Thus this whole considerable mining campaign could be brought into being on the following timetable:Day 1. Issue of proclamation reciting the character of the German attacks on the British coasts, shipping, and river mouths, and declaring that henceforth (while this continues), the Rhine is a mined and forbidden area, and giving neutrals and civilians twenty-four hours" notice to desist from using it or crossing it. 1.

After nightfall, deposit as many mines as possible by both methods, and keep this up night after night. The supply by that time should be such as to keep all methods of discharge fully employed. 2.

Begin the laying of the mines in the still-water ca.n.a.ls and river mouths, thereafter keeping the whole process working, as opportunity serves, until the kind of attacks to which we are being subjected are brought to an end by the enemy, or other results obtained.4. The decisions in principle required are:(a) Is this method of warfare justified and expedient in present circ.u.mstances?(b) Must warning be given beforehand, observing that the first shock of surprise will be lost? However, this is not considered decisive, as the object is to prevent the use of the river and inland waterways rather than mere destruction.(c) Should we wait till the air force are ready, or begin the naval action as soon as possible after March 12?(d) What reprisals, if any, may be expected, observing that there is not natural or economic feature in France or Great Britain in any way comparable with the Rhine, except our coastal approaches, which are already beset.5. It is desirable that the Fifth Sea Lord, who has the operation in charge, should go to Paris on Thursday, concert the details finally, and ascertain the reactions of the French Government. From the att.i.tude of M. Daladier, General Gamelin, and Admiral Darlan it is thought these will be highly favourable.W. S. C.

First Lord"s Minutes
SEPTEMBER, 1939.
First Lord to Secretary and to all Departments.
4.IX.39.
To avoid confusion, German submarines are always to be described officially as U-boats in all official papers and communiques.
First Lord to D.N.I. and Secretary.
6.IX.39.
1. This is an excellent paper and the principles are approved. However, in the first phase (say, September) when losses may be high, it is important that you show that we are killing U-boats. The policy of silence will come down later. The daily bulletin prepared by Captain Macnamara should, when possible, for the first week be shown to the First Lord, but should not be delayed if he is not available. It is of the highest importance that the Admiralty bulletin should maintain its reputation for truthfulness, and the tone should not be forced. The bulletin of today is exactly the right tone.2. When Parliament is sitting, if there is anything worth telling, bad or good, the First Lord or Parliamentary Secretary will be disposed to make a statement to the House in answer to friendly private-notice questions.These statements should be concerted with the Parliamentary Secretary, who advises the First Lord on Parliamentary business. Sensational or important episodes will require special attention of the First Lord or First Sea Lord.3. Lord Stanhope, as Leader of the House of Lords, should always be made acquainted with the substance of any statement to be made in the House of Commons upon the course of the naval war.Moreover, the First Lord wishes that his Private Secretary should keep Lord Stanhope informed during these early weeks upon matters in which his Lordship may have been interested. He should not be cut off from the course of events at the Admiralty with which he has been so intimately concerned.
First Lord to D.N.I. (Secret.) 6.IX.39.
What is the position on the west coast of Ireland? Are there any signs of succouring U-boats in Irish creeks or inlets? It would seem that money should be spent to secure a trustworthy body of Irish agents to keep most vigilant watch. Has this been done? Please report.
First Lord to D.C.N.S.
6.IX.39.
Kindly give me report on progress of Dover barrage, and repeat weekly.
First Lord to Controller.
6.IX.39.
1. What are we doing about bringing out old merchant ships to replace tonnage losses? How many are there, and where? Kindly supply lists, with tonnage. Arrangements would have to be made to dock and clean all bottoms, otherwise speed will be grievously cut down.2. I should be glad to receive proposals for acquiring neutral tonnage to the utmost extent.
First Lord to First Sea Lord, Controller and others.
6.IX.39.
1. It is much too soon to approve additional construction of new cruisers, which cannot be finished for at least two years, even under war conditions. The matter can be considered during the next three months. Now that we are free from all Treaty restrictions, if any cruisers are built they should be of a new type, and capable of dominating the five German 8-inch cruisers now under construction.2. Ask the D.N.C. at his convenience to give me a legend of a 14,000- or 15,000-ton cruiser carrying 9.2 guns with good armour against 8-inch projectiles, wide radius of action, and superior speed to any existing Deutschland Deutschland or German 8-inch-gun cruisers. It would be necessary before building such vessels to carry the United States with us. or German 8-inch-gun cruisers. It would be necessary before building such vessels to carry the United States with us.3. The rest of the programme is approved, as it all bears on U-boat hunting and ought to be ready within the year.4. I shall be very glad to discuss the general questions of policy involved with the Board.
First Lord to Prime Minister.
7.IX.39.
It seems most necessary to drill the civil population in completely putting out their private lights, and the course hitherto followed has conduced to this. But surely the great installations of lights controlled from two or three centres are in a different category.While enforcing the household black-outs, why not let the controllable lighting burn until an air-warning is received? Then when the hooters sound, the whole of these widespread systems of lighting would go out at once together. This would reinforce the air-raid warning, and when the all-clear was sounded, they would all go up together, telling everyone. Immense inconvenience would be removed, and the depressing effect of needless darkness; and as there are at least ten minutes to spare, there would be plenty of time to make the black-out complete.Unless you have any objection, I should like to circulate this to our colleagues.
First Lord to Controller.

Dates of Completion for Naval Construction: Tabular Statement Prepared by ControllerIn peace-time, vessels are built to keep up the strength of the Navy from year to year amid political difficulties. In war-time, a definite tactical object must inspire all construction. If we take the Navies, actual and potential, of Germany and Italy, we can see clearly the exact vessels we have to cope with. Let me therefore have the comparable flotillas of each of these Powers, actual and prospective, up to 1941, so far as they are known. Having regard to the U-boat menace, which must be expected to renew itself on a much larger scale toward the end of Having regard to the U-boat menace, which must be expected to renew itself on a much larger scale toward the end of 1940, the type of destroyer to be constructed must aim at numbers and celerity of construction rather than size and power. It ought to be possible to design destroyers which can be completed in under a year, in which case fifty at least should be begun forthwith. I am well aware of the need of a proportion of flotilla-leaders and large destroyers capable of ocean service, but the arrival in our Fleets of fifty destroyers of the medium emergency type I am contemplating would liberate all larger vessels for ocean work and for combat. 1940, the type of destroyer to be constructed must aim at numbers and celerity of construction rather than size and power.

The following ideas might be considered before our meeting at 9.30 Tuesday, September 12:1. Suspend for a year all work on battleships that cannot come into action before the end of 1941. This decision to be reviewed every six months.

(Vide the escape of the the escape of the Goeben Goeben across the mouth of the Adriatic, August, 1914.) across the mouth of the Adriatic, August, 1914.)5. I was distressed to see that till the end of 1940, i.e., sixteen months, we only receive ten destroyers, and only seven this year, and that there is a gulf of nine months before the subsequent six are delivered. However, we have taken over the six Brazilians which arrive during 1940 and mitigate this position. Let us go forward with all these to the utmost. These ships called "destroyers" have strayed far in design from their original role of "torpedo-boat destroyers," in answer to the French mosquito flotillas of the nineties. They are really small unarmoured cruisers with a far heavier stake in men and money than their capacity to stand the fire of their equals justifies. Nevertheless, for combat and for breasting ocean billows they have an indispensable part to play.6. Fast escort vessels: I now learn these are really medium destroyers of a thousand tons. The whole of this cla.s.s should be pressed forward to the utmost.7. We have also the whale-catcher type but this is 940 tons, which is a great deal where numbers are required. I doubt whether our dollars will enable us to place 40 of these in the United States. It would be much better to supplement them by a British-built programme of another type.8. I would ask that a committee of (say) three sea-officers accustomed to flotilla work, plus two technicians, should sit at once to solve the following problems:An anti-submarine and anti-air vessel which can be built within twelve months in many of the small yards of the country; 100 should be built if the design is approved. The greatest simplicity of armament and equipment must be arrived at, and a constant eye kept upon ma.s.s production requirements. The role of these vessels is to liberate the destroyers and fast escort vessels for a wider range of action, and to take over the charge of the Narrow Seas, the Channel, the insh.o.r.e Western Approaches, the Mediterranean and the Red Sea, against submarine attack.I hazard specifications only to have them vetted and corrected by the committee, viz.:500 to 600 tons.16 to 18 knots.2 cannons around 4-inches according as artillery may come to hand from any quarter, preferably of course firing high angle;depth-charges;no torpedoes, and only moderate range of action.These will be deemed the "Cheap and Nasties" (Cheap to us, nasty to the U-boats). These ships, being built for a particular but urgent job, will no doubt be of little value to the Navy when that job is done but let us get the job done.9. The submarine programme is approved as they still have a part to play.I shall be very grateful if you will give me your views on these ideas, point by point, to-morrow night.

As it is generally impossible to use the catapult aircraft in the open ocean, but nevertheless they would be a great convenience around the South American continental promontory, the question arises whether landing-grounds or smooth-water inlets cannot be marked down on uninhabited tracts or in the lee of islands, upon which aircraft catapulted from vessels in the neighbourhood could alight, claiming, if discovered, right of asylum. They could then be picked up by the cruiser at convenience. Perhaps this has already been done.

While I greatly desire the strengthening of this place [Scapa Flow] against A.A. attack, and regard it as a matter of extreme urgency, I consider the scale of eighty 3.7-inch guns goes beyond what is justified, having regard to other heavy needs. It is altogether out of proportion to lock up three regiments of A.A. artillery, etc. (comprising 6,200 men) for the whole war in Scapa. Scapa is no longer the base of the Grand Fleet, but only of three or four princ.i.p.al vessels. Alternative harbours can be used by these. The distance from Germany, 430 miles, is considerable. We must be very careful not to dissipate our strength unduly in pa.s.sive defence.I approve, therefore, of the additional sixteenth 3.7-inch as a matter of the highest urgency. But I think they should be erected by the Admiralty to avoid the long delays and heavy charges of the War Office Ordnance Board.The second twenty equipments should be considered in relation to the needs of Malta, as well as to the aircraft factories in England. This applies still more to the full scale of 3.7-inch guns, numbering forty-four. Their destination can only be considered in relation to the future war need.The light A.A. guns seem to be excessive, having regard to the heavy pom-pom fire of the Fleet. The searchlights and balloons are most necessary, as are also the two Fighter Squadrons. Do we not require a more powerful R.D.F. station? And should there not be an additional R.D.F. station on the mainland?In this case the urgency of getting something into position counts far more than making large-scale plans for 1940.Let me have reduced proposals with estimates of time and money, but without delaying action on the first instalments.Also a report of the A.A. defences of Malta, and also of Chatham.

It was very pleasant to see the aircraft carrier Argus Argus in the basin at Portsmouth to-day. The boats of this vessel have been sent to the C.-in-C., Home Fleet, but no doubt they could easily be replaced, and various guns could be mounted.
