This troop, I afterwards learned, were Sir Faithful Fortescue's troopers, who had but recently returned from Ireland; but, being unable to make their way to the Royal camp, had feigned to throw in their lot with the rebels until a favourable opportunity occurred to declare themselves openly. The next instant we were launched at full gallop upon the rebel cavalry, and of what happened during the next few moments I have but a dim recollection. It was cut, thrust, and parry. Men went down, still striking madly at their assailants, whilst riderless horses added to the confusion; but I knew that we had the best of the struggle, because we were ever advancing. Suddenly Firestone's horse plunged violently and fell on its knees, while its rider, slipping from off his saddle, rolled over, vainly endeavouring to throw himself clear of his floundering steed. At that moment one of the rebel dragoons, a veritable Anak, received a cut in the face, and, half blinded and maddened by the pain, he slashed furiously right and left. I wheeled to escape the resistless sweep of his sword, and, to my horror, I saw the weapon bury itself in Colonel Firestone's leg, shearing through jack-boot, limb, and even the saddle. The next instant I was urged onward by the rush of the combatants, and, much as I desired to, I was unable to help my luckless comrade. In a few minutes the rebel cavalry had broken and were in hot flight, while at their heels came our triumphant troopers, slashing and hewing at the fugitives without mercy. In the excitement of the pursuit time and distance were forgotten, till at length, breathless and triumphant, our cavalry gave up the chase, re-formed, and prepared to return to that part of the field of battle where, by the sound of heavy firing, we knew the contest still raged furiously. Before this was done, however, we were assailed by a body of rebel horse, which, launching itself on our rearguard, played havoc till driven off by superior numbers. When at length we regained our former position we were confronted by a solid phalanx of pikemen and musketeers, who presented such a redoubtable appearance that Prince Rupert hesitated to order a fresh charge. So with an occasional cannonade the battle ended just as night drew in upon the scene. "Hast seen Colonel Firestone?" asked Granville, as he wiped his dust-and blood-stained face with a handkerchief of delicate cambric. "Down yonder, I fear," I replied sadly, indicating the darkening plain on which the indistinct forms of the fallen could still be seen. "I saw him hurled from his horse with his leg shorn off at a single blow." "Perchance he still lives." "But I could scarcely believe that. He is more likely to have bled to death," said I. "Be that as it may, however, we'll make an effort to find him." And, giving our horses in charge of a camp follower, we sought out Sergeant Lawson, who willingly agreed to accompany us.
