We are too good friends (I hope) and the matters with which we are concerned are too serious (I’m sure) for anything but plain language.

This liquid fuel problem has got to be solved, and the natural, inherent, unavoidable difficulties are such that they require the drive and enthusiasm of a big man. I want you for this, viz. to crack the nut. No one else can do it so well. Perhaps no one else can do it at all. I will put you in a position where you can crack the nut, if indeed it is crackable. But this means that you will have to give your life and strength, and I don’t know what I have to give in exchange or in return. You have got to find the oil: to show how it can be stored cheaply: how it can be purchased regularly and cheaply in peace; and with absolute certainty in war. Then by all means develop its application in the best possible way to existing and prospective ships. But on the other hand, your Royal Commission will be advisory and not executive. It will assemble facts and state conclusions. It cannot touch policy or action. That would not be fair to those on whom I must now rely. Nor would you wish it. Its report must be secret from the public, and its work separate from the Admiralty. I cannot have Moore’s position[[20]] eclipsed by a kind of Committee of Public Safety on Designs. The field of practical policy must be reserved for the immediately responsible officers. Research however authoritative lies outside. All this I know you will concur in.

Then as to personnel. I do not care a d——n whom you choose to assist you, so long as (1) the representative character of the Committee is maintained, and (2) the old controversies are not needlessly revived. Let us then go into names specifically.

Further, ‘Step by step’ is a valuable precept. When you have solved the riddle, you will find a very hushed attentive audience. But the riddle will not be solved unless you are willing—for the glory of God—to expend yourself upon its toils.

I recognise it is little enough I can offer you. But your gifts, your force, your hopes, belong to the Navy, with or without return; and as your most sincere admirer, and as the head of the Naval Service, I claim them now, knowing well you will not grudge them. You need a plough to draw. Your propellers are racing in air.

Simultaneously with the setting up of this Commission we pursued our own Admiralty search for oil. On the advice of Sir Francis Hopwood and Sir Frederick Black[[21]] I sent Admiral Slade with an expert Committee to the Persian Gulf to examine the oil fields on the spot. These gentlemen were also the Admiralty representatives on the Royal Commission. To them the principal credit for the achievement is due. At the later financial stage the Governor of the Bank of England, afterwards Lord Cunliffe, and the director of the Anglo-Persian and Royal Burmah Oil Companies were most serviceable. All through 1912 and 1913 our efforts were unceasing.

Thus each link forged the next. From the original desire to enlarge the gun we were led on step by step to the Fast Division, and in order to get the Fast Division we were forced to rely for vital units of the Fleet upon oil fuel. This led to the general adoption of oil fuel and to all the provisions which were needed to build up a great oil reserve. This led to enormous expense and to tremendous opposition on the Naval Estimates. Yet it was absolutely impossible to turn back. We could only fight our way forward, and finally we found our way to the Anglo-Persian Oil agreement and contract which for an initial investment of two millions of public money (subsequently increased to five millions) has not only secured to the Navy of a very substantial proportion of its oil supply, but has led to the acquisition by the Government of a controlling share in oil properties and interests which are at present valued at scores of millions sterling and also to very considerable economies, which are still continuing, in the purchase price of Admiralty oil.

All forecasts in this speculative market are subject to revision. The figures set out below are recent and authoritative.[[22]]

On this basis it may be said that the aggregate profits, realised and potential, of this investment may be estimated at a sum not merely sufficient to pay for all the programme of ships, great and small of that year and for the whole pre-war oil fuel installation; but are such that we may not unreasonably expect that one day we shall be entitled also to claim that the mighty fleets laid down in 1912, 1913 and 1914, the greatest ever built by any power in an equal period, were added to the British Navy without costing a single penny to the taxpayer.

Such is the story of the creation of a Fast Division of five famous battleships, the Queen Elizabeth, Warspite, Barham, Valiant and Malaya, all oil-driven, each capable of steaming a minimum of 25 knots, mounting eight 15–inch guns and protected by 13 inches of armour. It is permissible to look ahead and see what happened to these ships in the Battle of Jutland. Let us take the accounts of the enemy.
