We were given but a few days to explore the country at our leisure. The enemy apparently had determined to make their first stand on the line of the Selle river, a very definite obstacle. Le Cateau itself was doubtful territory.

A series of conferences was held at brigade headquarters, which had suddenly jumped forward to Serain. It was determined to attack on the 17th. Now that we had reached good roads and open country my tanks were not required to carry supplies for the fighting tanks, but, as a measure of precaution, I was instructed to send a section forward to Maurois, a ten-mile trek from Genève. Parslow's tanks completed the trek without incident on the 15th.

I motored up to see him, and every yard of the road was for me a solemn triumph. We were avenging the confused retreat of the British Army on the afternoon and night of the first battle of Le Cateau; we were driving through really clean unshelled country, which might never have been touched by the finger of war if it had not been for the craters blown at the cross-roads and the occasional corpse by the roadside; and never in my life have I seen happier people, men and women more flustered and confused with happiness, than the thin underfed villagers who stood gazing in the crowded main street of Maretz.

Short of Maurois village the Germans had blown into the cutting the road-bridge over the railway from Cambrai to St Quentin. The traffic was being diverted, when we arrived on the scene, over heavy fields to a level crossing, and the engineers were working against time to construct a new bridge capable of bearing the heaviest transport. It had been raining, and the men were finding it difficult indeed to haul the great girders into position. A couple of hundred yards away were Parslow's tanks. The remedy was obvious. A tank was brought round on to the rails and spent a profitable hour in doing a job which would have taken fifty men a full day. The bridge was completed rapidly, and the traffic once more flowed steadily over the bridge instead of floundering over the fields.

On the 17th and 18th Parslow's tanks were not required. On the 19th they trekked back to Genève. The 4th Tank Brigade was being relieved by the 2nd Tank Brigade. We expected orders to move to Hargicourt for entrainment, and we made an expedition over the log-road to discover the whereabouts of the ramp. But a railway accident outside Cambrai delayed the arrival of the 2nd Carrier Company,​—​to our disgust we were ordered to remain temporarily with the 2nd Tank Brigade.

We became involved at once in our last battle of the war. From the 17th to the 20th we had straightened our line in a series of fierce and costly little attacks. The enemy had been driven definitely from Le Cateau and now lay just beyond the outskirts of the town. To the west of the town we had crossed the Selle. The Army Commander decided to throw the enemy back to the Mormal Forest by a grand attack on a fifteen-mile front. I received orders from the 2nd Tank Brigade to assist the XIIIth Corps by carrying supplies.

I instructed Parslow's section, which had just completed a ten-mile trek, to return with Thomas's section to the camp by Maurois Station, and when they were on their way I reported at Corps Headquarters. I arranged with the Corps Staff that Thomas's section should operate with the 33rd, 34th, and 35th Infantry Brigades of the 11th Division, while Parslow should help the 25th Division. The Corps further requested urgently that any spare tanks which I might have should be detailed to carry ammunition for the 104th Army Brigade R.F.A., the guns of which could not be reached by horse transport without difficulty on account of the nature of the ground. I brought up Harland from Genève, gave him two tanks, and ordered him to carry on.

On the afternoon of the 20th I established my advanced headquarters in an orchard, quarter of a mile from the bridge which we had helped to construct. After mess we all attended a first-rate "show" given by the Divisional Troupe of the 25th Division, and returned to our camp greatly encouraged, but a trifle unhappy that we had not billeted ourselves in one of the many excellent houses in Maurois.

That night one officer at least was disturbed in his slumbers. The enemy shelled Maurois persistently, sending over a few shells to the neighbourhood of the bridge. Finally a large aeroplane bombed along the main road, dropping one group just short of the camp, and another group, intended presumably for the bridge, between the bridge and the camp. The aeroplane was flying so recklessly low​—​it was a clear night with a moon​—​that for once our machine-gunners brought her down in a field about a mile beyond the bridge.

Much damage had been done in Maurois. We were thankful that we were in tents outside the village and had not been tempted by the houses. One shell had exploded just behind the hall in which the concert had been held. For such shelling and bombing the casualties were heavy.
