Yet we came back from our reconnaissance in the firm belief that tanks could break through this fortification without any difficulty at all. The ground was hard chalk, and no amount of rain could make it unfit for our use. Natural and artificial obstacles could be surmounted easily enough or avoided. Given sufficient tanks and the advantage of surprise, there was no earthly reason why we should not go straight through to Cambrai. What could stop us? The wire? It did not affect us in the slightest. The trenches? They were a little wide, but we knew how to cross them. Guns? There were not many, and few would survive the duel with our own artillery. Machine-guns or armour-piercing bullets? The Mk. IV. tank was practically invulnerable. If the infantry were able to follow the tanks, the tanks would see them through the trench systems. In open country it would be for common-sense and the cavalry, until the enemy filled the gap with his reserves.
We were only troubled by the thought of Bourlon Wood, which, from its hill, dominated the whole countryside between Havrincourt and Cambrai. But Bourlon Wood was only a matter of 7000 yards behind the German lines. If we were to break through at all, we should take the wood in our stride on the first day.
"Unless the Boche catches on before the show, it's a gift!"
We returned to Wailly bubbling over with enthusiasm. The last rehearsals were completed, and our future comrades, the 6th Black Watch and the 8th Argyll and Sutherland Highlanders, appeared implicitly to trust us. We tuned our engines and practised with the wily "fascine."
Fascine is the military term for "faggot." Each of our fascines was a huge bundle of brushwood, weighing over one ton. By an ingenious mechanism it could be hoisted on to the roof of the tank. When a dangerously wide trench was reached, the driver pulled a rope, the fascine gently rolled off the tank into the trench, and the tank crossed at its ease. It was a simple device that produced an astonishing amount of bad language. Entraining was hideously complicated. Dropping the fascine on to the truck in front of the tank requires care and precision, while obviously if a fascine refuses to be picked up again, tanks are prevented from coming off the train....
