By the time we were on the move again it was full daylight. We dropped into action again three or four times, but were forced to resume our retirement, harassed all the time by the Germans. During the retirement we had several shots at German aeroplanes, which were flying about spying out our positions and signalling them to their own people; but field-guns are not much use against aircraft, because the muzzles cannot be elevated sufficiently high. You need howitzers for the work, because they are specially made for high-angle fire and can throw their shots right over aeroplanes. We were retiring from the Monday till the Wednesday; then we got the order to drop into action again. That was at eight o’clock in the morning, and by that time we were at Cambrai, a good distance from Mons, as you can see from the map. Mons was bad, but Cambrai was far worse. We had been retreating all the time, day and night, fighting a heavy rearguard action, so that men and horses were utterly worn out. Again the artillery did splendid work, and had to pay for it. The 6th Battery had lost two guns and a waggon at Mons, because the horses were killed, and they also had another gun put out of action. They lost a further gun at Cambrai, and the battery was almost completely cut up, but for their loss we in the 23rd Battery were able to make up in a way. Our own guns were concealed so cleverly that the Germans could not find them anyhow. The nearest they could get to us was about fifty yards in front or fifty yards behind, and in dropping shells fifty yards make a lot of difference, as the Germans found to their cost. Our concealed battery did heavy execution amongst them, and they deserved all they got. When I was clear of the valley I got two fresh horses; but at Cambrai, on the Wednesday, they were both killed. A shell burst and took off the head of the riding horse, and bullets killed the off horse, so I was dismounted again; and not a few of my chums were in the same unfortunate position. Cambrai was the last battle we had before we turned the tables on the Germans, and began to drive them back at the Marne, where a tremendous fight went on for many days. Altogether we had been retiring pretty well a week, and we rejoiced when the advance began. The advance made new men of us, especially when we saw what the Germans had done. There were plenty of wrecks of our convoys on the roads, where the enemy had got at them. That sort of thing was all right, of course, and came in fairly enough in warfare; but it made our blood boil to see the wanton damage that these so-called civilised soldiers had committed on a people who had done no greater crime than defend their hearths and families. You ask about German cruelties and barbarities. Well, I will tell you something about what I saw myself, and people can form their own opinion as to what generally happened.
