Visibility fair. Only one enemy plane was seen today and no balloons.

3rd Canadian Divisional Artillery war diary records:
BRAQUEMONT - Visibility fair on account of mist. Enemy artillery harassed LOOS during the night and became very active in counter battery work. The shells seem to be coming from a new direction to the south and the shelling is very persistent. Our aeroplanes were active all day; only one or two enemy planes were observed. Much movement has been reported in back areas. Our batteries took many targets with good results, guns having been registered on points where movement had been seen and the crews standing to.
