A ball had passed through his breast.

The other, who was safe and sound, continued his way toward the camp.
D'Artagnan was not willing to abandon his companion thus, and stooped to raise him and assist him in regaining the lines; but at this moment two shots were fired.

One ball struck the head of the already-wounded guard, and the other flattened itself against a rock, after having passed within two inches of d'Artagnan.
The young man turned quickly round, for this attack could not have come from the bastion, which was hidden by the angle of the trench.

The idea of the two soldiers who had abandoned him occurred to his mind, and with them he remembered the assassins of two evenings before.

He resolved this time to know with whom he had to deal, and fell upon the body of his comrade as if he were dead.
He quickly saw two heads appear above an abandoned work within thirty paces of him; they were the heads of the two soldiers.
