Every man in the tank was shouting and yelling with the excitement of the thing and we were tossed up against each other like loosened peas in a pod. Only Joffre remained perfectly cool. Somehow she maintained a firm seat on my swaying shoulder and as I glanced around to peer at her she was calmly licking a paw and then daintily wiped her face.

Suddenly out of a very clever camouflage of tree branches and shrubbery a German machine-gun emplacement was revealed. The bullets stormed and rattled upon the tank. But they did themselves a bad turn by revealing their whereabouts, for we made straight for the camouflage and went over that battery of machine guns, crunching its concrete foundation as if it were chalk.

"British blood is calling British blood"

Then we turned about and from our new position put the Germans under an enfilade fire that we kept up until every evidence was at hand that the Oxfords and Bucks and supporting battalions were holding the trenches.

But this was only preliminary work cut out for the tank to do. I had special instructions and a main objective. This was a sugar refinery. It was a one-storied building of brick and wood with a tiled roof. It had been established as a sugar refinery by the Germans before the war and when this occasion arose blossomed as a fortress with a gun aimed out of every window.

To allow it to remain standing in hostile hands would mean that the trenches we had won could be constantly battered. Its removal was most desirable. To send infantry against it would have involved huge losses in life. The tank was deemed the right weapon.

It was.
