The cause was this. The brigade with which the friends were connected was sent on a _reconnaissance_, and they felt the enemy strongly before retiring, which at last they were compelled to do precipitately. It so happened that Hilland commanded the rear-guard. In an advance he ever led; on a retreat he was apt to keep well to the rear. In the present instance the pursuit had been prompt and determined, and he had been compelled to make more than one repelling charge to prevent the retiring column from being pressed too hard. His command had thus lost heavily, and at last overwhelming numbers drove them back at a gallop. Graham, in the rear of the main column, which had just crossed a small wooden bridge over a wide ditch or little run through the fields, saw the headlong retreat of Hilland's men, and he instantly deployed his company that he might check the close pursuit by a volley. As the Union troopers neared the bridge it was evidently a race for life and liberty, for they were outnumbered ten to one. In a few moments they began to pour over, but Hilland did not lead. They were nearly all across, but their commander was not among them; and Graham was wild with anxiety as he sat on his horse at the right of his line waiting to give the order to fire. Suddenly, in the failing light of the evening, he saw Hilland with his right arm hanging helpless, spurring a horse badly blown; while gaining fast upon him were four savage-looking Confederates, their sabres emitting a steely, deadly sheen, and uplifted to strike the moment they could reach him. With the rapidity of light, Graham's eye measured the distance between his friend and the bridge, and his instantaneous conviction was that Hilland was doomed, for he could not order a volley without killing him almost to a certainty. At that supreme crisis, the suggestion passed through his mind like a lurid flash, "In a few moments Hilland will be dead, and Grace may yet be mine." Then, like an avenging demon, the thought confronted him. He saw it in its true aspect, and in an outburst of self-accusing fury he passed the death sentence on himself. Snatching out the long, straight sword he carried, he struck with the spur the noble horse he bestrode, gave him the rein, and made straight for the deep, wide ditch. There was no time to go around by the bridge, which was still impeded by the last of the fugitives.
