On the right of the attack, zero was at 5.45. The 9th Corps, which, it will be remembered, was supported by four sections of the 10th Tank Battalion, pushed forward and captured Catillon, where the Tanks fought a particularly good action. The infantry were able to cross the Sambre at this place, capturing a lock some two miles to the south of it. By two hours after zero two battalions of infantry were east of the river. The Tanks with the 13th Corps were also extremely successful, especially in the neighbourhood of Hecq, Preux and the north-western edge of the Forest of Mormal. An account of the fighting on this central part of the line is given in the Tank Corps Intelligence Summary. “The early morning was fine and clear, but a dense mist came up with the dawn and persisted until about 8.30. In addition, the country S.W. of Mormal Forest is peculiarly enclosed with thick orchards, quick-set fences and hedgerow trees, confining visibility to no more than fifty yards or so, under the best conditions. The infantry largely depended on the Tanks to give them their direction, and many of the latter had to steer exclusively by compass. By this means they were able to keep approximately to their allotted routes, and were of considerable help to the infantry in breaking through the dense hedges (some wired) and in dealing with machine-guns. In places the enemy barrage came down heavily with a high proportion of gas, whilst elsewhere it was inconsiderable. Resistance also was unusually ‘patchy,’ some few M.G. posts holding out well, whilst many others, though well sited and camouflaged, were found not to have fired a round. A show of resistance was put up at Landrecies bridge by some 300 German infantry and machine-gunners, but they gave in when outflanked by the crossing of the canal on rafts further to the south. The enemy had lined some of the hedges with deep and very well camouflaged rifle-pits, which here and there were held in strength. The main body of the enemy, however, appears to have been withdrawn a kilometre or so in rear of his forward positions just prior to our attack. French inhabitants of the most forward villages state that he started withdrawing at five o’clock this morning. In a number of instances the enemy was found hiding, unarmed, awaiting an opportunity to surrender. In one village over fifty Germans emerged from the house cellars where they had been hiding together with the inhabitants. Other Germans attempted to hide themselves in trees and were dealt with with case shot. A number of anti-Tank rifles were found in rifle-pits, etc., but appear to have been made little or no use of. There were instances of detached field guns being sited to enfilade hedges and cover crests, but so far no reports have come in as to their effect--if any. One Brigade operating with Tanks is reported to have had over 350 prisoners through its
