Tomorrow the Canadian Corps will attack Hill 70, east of the village of Loos which has been in German hands since September 1915.
In preparation for the attack, the RFC carried out carefully organized attacks. Overnight 10 Squadron bombed railway junctions and billets east of the Lens front, notably Carvin, Berclau, and Oignies in their Armstrong-Whitworths.
At Oignies a fire was started, and the pilot whose bombs caused the blaze went down to 500 feet, and finding that a number of men had gathered, dispersed them with his machine-gun.
Oignies was attacked again today by day-bombers from 25 Squadron in their DH4s, who dropped 28 20-lb. bombs on the village. The same squadron, late in the evening, attacked the German aerodrome at Dorignies, north of Douai, with forty 20-lb. bombs.
27 Squadron attacked Phalempin aerodrome from which aircraft worked over the Lens sector—in their Martinsydes with four 112-lb. and 32 20-lb. bombs).
During the night, 10 Squadron bombed the head-quarters and rest billets of the German divisions which were to be attacked. Fifty-one light-weight bombs were dropped by the squadron on Annay, Courrieres, Oignies, Carvin, Epinoy, and Pont-a-Vendin.
