expenditure of projectiles, behind strong intrenchments. On the 12th the
result had none the less been attained, and our two centre armies were
solidly established on the ground gained.

On the 10th inst. the Eighth and Fifteenth German Army Corps
counter-attacked, but were repulsed. On the 11th our progress continued
