Riding forward into Masnieres, General Seely received word that the attacking troops had secured their objectives, and accordingly the brigade advance guard, the Fort Garry Horse, entered the town and managed to get across the river bridge in the main street. The canal bridge beyond, however, had been broken down, either by the weight of a tank or blown up by the enemy during the crossing of one of these machines. At any rate, one of our tanks had plunged through into the canal beneath, and, without very radical repair, the bridge was impassable to mounted men. Another bridge, in a rather better condition, was discovered to the south-west, and Major Walker, of the Machine Gun Squadron, commandeered the help of every available man, including civilians and German prisoners, and by three o'clock the bridge was strong and practicable. This work was accomplished under very heavy fire. Upon the completion of the bridge, "B" Squadron of the Fort Garry Horse, under the command of Captain Campbell, pushed forward across the canal and attacked the enemy's line upon the ridge, while the remainder of the regiment prepared to follow. But conflicting statements arrived from the infantry--there had been a check--and before the rest of the mounted men could advance, Colonel Patterson, commanding the Fort Garry Horse, received orders instructing him not only to remain west of the canal, but to withdraw any of his troops that might have crossed. Colonel Patterson immediately sent messengers after "B" Squadron, but the orderlies were unable to deliver their instructions. The Canadian troopers had wasted no time--opportunity had been denied them too long--and there had been little delay in getting to grips with the enemy. They were well away. Captain Campbell's men came under machine-gun fire directly they left Masnieres, and for a few minutes the horses were hard put to it in the marshy ground about the canal. Before them the infantry had cut a gap in the German wire, and winning through the swamp they charged for this at the gallop, taking little heed of the heavy fire. Casualties were rather heavy at the gap. Captain Campbell went down, and command was taken by Lieutenant Strachan. There was no delay. Sweeping through the gap, Strachan led his men north towards Rumilly, and soon encountered the camouflaged road just south-east of the town. This obstacle was negotiated successfully enough, with some slight damage to the screens and an occasional telephone wire, and, forming in line of troop columns, the men went forward at the gallop to an objective dear to any cavalryman's heart. A battery of field-guns lay before them.
