1 Wing RFC assisted First Army in an offensive near Chapelle St. Roch-Rue d’Ouvert today.
At the end of May the First Army had taken over from the French a stretch of line from a point south of the La Bassee Canal to the neighbourhood of Loos, and the squadrons of the First Wing were redistributed accordingly.
Sir Douglas Haig had originally wanted to resume the offensive against the village of Loos, but after a study of his air reconnaissance reports he suggested that an offensive against Chapelle St. Roch-Rue d’Ouvert offered better chances of success, and he outlined proposals for an attack on both sides of the canal there. Unfortunately there was insufficient ammunition, and so the attack was confined to the north of the canal.
The assault by the First Army commenced early this morning. Squadrons from 1 Wing provided tactical reconnaissance and artillery observation. The RNAS also lent two aeroplanes with pilots and observers. Given the paucity of ammunition, particular attention was paid to air co-operation between 1 Wing and No. I Group, Heavy Artillery Reserve.
