On the 11th of October, the enemy was discovered drawn up in a strong line across the passage between Valicour, one of the numerous islands on the lake, and the Western land; and so well concealed by the island, that the squadron had nearly passed without observing them. They had fifteen vessels, carrying ninety-six guns, fourteen of which were eighteen-pounders, (eight of them traversing), and twenty-three twelves. General Arnold commanded. The _Carleton_, being nearest to the enemy, attacked at once, though her force was only twelve six-pounders. Unfortunately, from the state of the wind, no other vessel could come to her assistance, and she was obliged to engage the whole force of the enemy single-handed. Sir Guy Carleton saw her desperate position with extreme anxiety, but it was impossible to bring up the squadron, and he could only send in the artillery-boats to support her. Meantime she was suffering most severely. Very early in the action, Mr. Brown lost an arm; and soon after, Lieutenant Dacres fell, severely wounded and senseless. He would have been thrown overboard as dead, but for the interference of Mr. Pellew, who now succeeded to the command. He maintained the unequal contest, till Captain Pringle, baffled in all his efforts to bring up the squadron, made the signal of recall, which the _Carleton_, with two feet water in her hold, and half her crew killed and wounded, was not in a condition to obey. In attempting to go about, being at the time near the shore, which was covered with the enemy's marksmen, she hung in stays, and Mr. Pellew, not regarding the danger of making himself so conspicuous, sprang out on the bowsprit to push the jib over. The artillery-boats now towed her out of action, under a very heavy fire from the enemy, who were enabled to bear their guns upon her with more effect, as she increased her distance. A shot cut the towrope, and Mr. Pellew ordered some one to go and secure it; but seeing all hesitate, for indeed it appeared a death-service, he ran forward and did it himself. The result of the action was far beyond anything that could have been expected from the excessive disparity of the force engaged; for the _Carleton_, with the assistance of the artillery-boats, had sunk the _Boston_ gondola, carrying an eighteen pounder and two twelves; and burnt the _Royal Savage_, of twelve guns, the largest of the enemy's schooners. Arnold escaped in the night. The squadron pursued, and on the morning of the 13th overtook him, within a few leagues of Crown Point. After a running fight of two hours the four headmost vessels of the enemy succeeded in reaching Crown Point, and sheltering themselves in the narrow part of the lake beyond it. Two others, the _Washington_ and _Jersey_, were taken; and the rest were run on shore and burnt by their own crews. The enemy then set fire to their works on Crown Point, and abandoned it.
