At this battle all the available Tanks (about four hundred) were being used.

There were no reserves.

So the General Commanding led the attack, flying the Tank Corps flag.

He came safely through the attack, which undoubtedly owed some measure of its success to the inspiration which this act gave to the troops." A quiet account!--given by a man who was certainly not very far away from his General in the affair.

Let me supplement it a little by the story of Mr.Philip Gibbs, who seems to have seen as much as any correspondent might, of this wonderful "show" of the Tanks.
"For strange, unusual drama, far beyond the most fantastic imagination, this attack on the Hindenburg line before Cambrai has never been approached on the Western Front; and the first act began when the Tanks moved forward, before the dawn, towards the long wide belts of wire which they had to destroy before the rest could follow.
These squadrons of Tanks were led into action by the General Commanding their corps, who carried his flag on their own Tank--a most gallant gentleman, full of enthusiasm for his monsters and their brave crews, and determined that this day would be theirs.
