But when each of the second line of Tanks stopped, ducked its head, laid its “stepping stone” in the trench and crawled easily over it, the enemy completely lost his balance.

All along the line men fled in panic. Only at a few tactical points did our onrush meet with any real opposition. The surprise, the novel tactics, the crushing onrush of the Tanks proved too much in those first confounding minutes for one of the best fighting armies the world had ever seen.

The “Hilda” reached the outposts line in the van of the battle; the resistance here was only slight, but General Elles succeeded in picking up a few targets which he pointed out to the gunners. It is reported that he did most of his observing with his head thrust up through the hatch in the roof of the Tank, using his feet in the gunner’s ribs to indicate targets.

Once the Tanks were astride the enormous Hindenburg ditch, the enemy only offered resistance in a few places. The “Hilda,” still carrying the flag which had been several times hit but not brought down, went on to her first objective line, which included the main Hindenburg front, and support lines.

But the General’s holiday was over. The great problem had been triumphantly solved.

The next most pressing need would be for reorganisation.

If any of the Tanks were required to operate again the next day, that reorganisation must be begun at once. So reluctantly leaving the “Hilda” to carry on to further objectives, the General came back on foot, somewhat impeded by various parties of “unmopped up” Germans who insisted on surrendering to him. By the afternoon, General Elles was back at his Headquarters, functioning by telephone and shorthand-typist in the manner usual to Generals.

Here and there, after the first rush, a desperate handful of the enemy would be rallied by their officers to defend some point of vantage.

At Lateau Wood on the right of the attack heavy fighting took place, including a duel between a Tank and a 5.9 in. howitzer. Turning on the Tank the howitzer fired, shattering and tearing off most of the right-hand sponson of the approaching machine, but fortunately not injuring its vitals; before the German gunners could reload, the Tank was upon them, and in a few seconds the great gun was crushed in a jumbled mass amongst the brushwood surrounding it.

A little to the west of this wood the Tanks of “F” (the 6th) Battalion, which had topped the ridge, were speeding down on Masnières. One approached the bridge, the key to the Rumilly-Seranvillers ridge, upon the capture of which so much depended. The bridge had, as the Tank Commander knew, been damaged either by shell-fire or by the German sappers. It was, however, most important that he should cross, and he very pluckily, therefore, went for it. As the Tank neared the centre of the bridge, there was a rending of steel girders—the bridge had broken, and as it collapsed the Tank disappeared into the waters of the canal. Other Tanks arriving, and not being able to cross, assisted the infantry to do so by opening a heavy covering fire.
