Later, the H.B.M.G.C.

Finally, the Tank Corps.

The Admiralty: (1) In its capacity as the Land Ship Committee, and (2) as Squadron 20 of the R.N.A.S.

The Ministry of Munitions: (1) In its capacity as the Trench Warfare Department; (2) in its capacity as the Inventions Department. (3) Later, as the Mechanical Warfare Supply Department (really another Tank Committee). (4) Later still, as the Tank Supply Department.

The successive Main Tank Committees: (1) The Joint Naval and Military Committee (which did not survive Act I.). (2) The Tank Supply Committee, afterwards called the Advisory Committee of the Tank Supply Department, and divided into a main committee and a sub-committee. (It was this sub-committee which afterwards formed the backbone of the very active and occasionally criticised M.W.S.D., before referred to). Later, (3) after a gap, the First Tank Committee; (4) the Second reconstructed Tank Committee.

III

We find that the period from August 1915 to February 1916 constitutes a kind of Act I. in the history of Tank administration and manufacture, for the 1914 and early 1915 period is too dim and legendary to serve as anything but prologue.

During the whole of the Act I. period it was the Admiralty and the Joint Land Ship Committee which played the “leads.”

It was the Admiralty which defrayed the whole cost of the extensive experimental work and provided the necessary personnel, and it was by members of the Joint Committee in consultation that the Mark I. Tank, “Mother,” was ultimately designed.
