Toné on army patrol in Morane Scout 178A. “Lost DH in clouds. Saw FE at 6,000ft so I climbed up to it but found I could not see the ground. Came down under the clouds over Peronne. Clouds then were at 3,500ft. Later in a thick layer of clouds came up at 500ft. Very active movements by our troops and heavy shelling on the front between Martinpuich and Flers”.
