That wonderful results are obtained by the French airmen whose duty it is to photograph positions and movements from above, our readers have frequently had pictorial proof. The example here reproduced, taken at a comparatively low altitude, is particularly fine in the amount of detail discernible, and will repay close inspection. It shows reinforcements arriving in the French trenches at 3 p.m. on September 17, during the attack on Vermand-Ovillers. An official french communiqué afterwards stated: "South of the Somme, our troops, passing to the attack about 2:30 p.m. . . gained important successes. The villages of Vermand-Ovillers and Berny were conquered in the course of a brilliant assault. . . All the ground comprised between Vermand-Ovillers and Deniécourt on the one side and between Deniécourt and Berny on the other, defended by several strongly organized systems of trenches, fell into our hands after a desperate struggle . . .700 unwounded prisoners, including 15 officers, have been counted."
