Bath Dam (Dam 66) was, perhaps, the worst job the R.E. had to tackle in the whole sector, as the enemy made a special target of it. This dam controlled the flow of the River Yser into the Yser Canal, and by its means the water in the flooded polders was kept at a sufficiently high level to form a military obstacle. On October 31 a breach fifteen feet in width was made by 8-inch shells, causing the flooding of the country up to the third-line trenches. Lieutenant Mellor, 427 Field Company, promptly organized a working-party of sappers and men of the 6th and 7th Manchesters, and at once started on its repair, the enemy, of course, doing their utmost to obstruct. The indefatigable C.R.E., Lieut.-Colonel D. S. MacInnes, D.S.O., who never failed to turn up at any hour of the day or night when his presence could assist and inspire, took charge of one of the reliefs, and set an example of energy and coolness under fire.[10] The breach was rebuilt with sandbags before the rapidly rising tide could take effect. On November 3 York Dam was damaged, but the same night a working-party closed the gap with 2000 sandbags; but on November 13 both York and Hull Dams were heavily shelled and wiped out, and on the 15th, Dam 66 and Mellor Dam were blown up by concentrated artillery fire. The height of the tide hindered the work of repair, which on this account could not be completed before the Division was relieved. On October 31 Lieutenant K. MacIver, of “B” Battery, 211 Brigade, R.F.A., during a bombardment of his battery position, which destroyed two of the three guns, ran out to attend to a wounded man of another unit. He was knocked down by a shell and his left arm rendered useless, but, assisted by a driver, he removed the wounded man to safety. Soon afterwards two dumps caught fire and MacIver, foreseeing that the flames would assist a hostile plane to register the battery, ran out into the shelled area and, though one arm was useless, he extinguished the flames at both dumps. On November 2 Private T. Brotherton, 5th E. Lancs., while in charge of a limber taking rations up the line, was wounded by a shell which dropped three yards in rear of his vehicle. Although in great pain and under heavy shelling all the time, he coolly unhooked his mules, one of which had been injured, refusing attention for himself until he had done everything possible for the animals. He then had his wounds dressed, and obeyed the order to report to the nearest Field Dressing Station with great reluctance, as he wished to return to his transport lines for another mule so that he could carry on. On the same day Crowder Bridge was shelled while a party of the 6th Manchesters was in the act of crossing singly, and one man was seriously wounded and knocked into the water. Sergeant E. E. Parry, R.A.M.C., attached to the 6th Manchesters, at once rushed on to the bridge, and remained supporting him and crouching over him until the shell-storm ceased. The man was
