The 53rd Brigade, fighting upon the left of the 55th Brigade, was as heavily engaged on March 23 as the other units of the Third Corps on the south side of the canal. At noon they had lent the 10th Essex to support their neighbours, and they consisted henceforth of only two weary battalions, the 6th Berks and 7th West Kents. At 3 o'clock in the afternoon they were heavily attacked and were pushed slowly back, struggling hard to keep the line. Major Tween led a counter-attack of his battalion headquarters, and checked the German advance at a critical moment, but was mortally wounded in the gallant endeavour. The two battalions were so weak that they had been telescoped into one, but good steel remains tough be it ever so thin, and the line still held. At 5.30 the 9th French Cuirassiers, long-booted giants, came up to help them, as did the 79th Field Company and various small details. At 7 the remains of the 55th Brigade were falling back through their ranks. When they had passed, the 53rd was also withdrawn as far as Commenchon, while the 55th reassembled at Bethencourt to the north. Three gallant Cuirassier regiments of the 1st French Cavalry Division covered the rear. All {188} the troops that night were worn to rags, for it is to be remembered always that the great local disparity of force enabled the Germans to bring up perpetually lines of perfectly fresh men with a new impetus and inspiration, against men, many of whom had been gassed on the first day, and who were now weary to death and hardly able either to stand or to think, to order or to understand an order. On the whole long, tormented, struggling line there was no time or place where the pressure was greater than here. In spite of all the ardour of the attack the stubborn constancy of the defence may be measured by the fact that, save for one battery which was destroyed by shell-fire upon the afternoon of the 23rd, no guns were lost in this corps either upon March 22 or 23. On the other hand, so great had been the destruction of machine-guns, especially upon the first day, that only two were left out of forty-eight in the Eighteenth Division, though these were augmented by six new ones on March 24.
