As soon as the French, British, and Belgians—for they were
all exposed to the poisoned-gas attack, though the French experienced it first—recovered from the surprise caused by the new tactics, vigorous counter-attacks were organized and a great deal, though not all, of the ground lost was recovered. By Tuesday the Allies had completely made good their parities, and we may now sum up the situation by saying that the Germans have gained rather less ground than we gained by the battle of Nenve Chapelle and the attack on Hill 60, and have paid a very heavy prioe in the way of losses. The Allies, of course, have lost heavily also, but nothing like as much as the Germans, who brought up very large rein- forcements for their poison campaign, and threw them in mass formation upon our trenches.
