On the thirteenth of August, Allen captured a vessel from Oporto, loaded with wine. Towards morning he set her on fire, and by the light of her blazing spars stood away under easy sail. Soon after daylight he saw a large brig of war bearing down upon him, perfectly covered with canvas. He immediately took in sail to allow her to close, and when she came within close range gave her a broadside. As the vessels continued to approach the firing became more rapid and destructive. In four minutes Captain Allen was mortally wounded by a round shot, carrying off his leg. His officers immediately caught him up to carry him below, but he ordered them back to their posts. In a short time, however, he fainted from loss of blood and was taken away. Four minutes after, the first lieutenant, Watson, was struck in the head by a grape shot, and he too was taken below. There was then but one lieutenant left, Lieut. H. Allen, who though alone, fought his ship gallantly. But the rigging was soon so cut up that the vessel became unmanageable, and the enemy chose his own position. In about a quarter of an hour Mr. Watson was able to return on deck, when he found the brig rolling helplessly on the water, a target for the Englishman's guns. He however determined to get alongside and board, but all his efforts to do so were abortive, and he was compelled to strike his colors. His victorious adversary was the Pelican, a brig of war a fourth larger than the Argus. Unwilling to believe that this great disparity of force was a sufficient reason for the defeat, the Americans endeavored to account for it in other ways. It was said that the sailors succeeded in smuggling wine from the brig burned a few hours before, and were not in a condition to fight--others that they were so overcome with fatigue that they nodded at their guns. Her fire was certainly much less destructive than that of other American vessels, which one of the officers on board said was owing to the powder used. Getting short of ammunition, they had taken some powder from an English vessel bound to South America. This being placed uppermost in the magazine, was used in this engagement. It was afterwards ascertained to be condemned powder, going as usual to supply South American and Mexican armies. In proof of this, it was said that the Pelican's hull was dented with shot, that had not force enough to pierce the timbers. The superiority of the English vessel in size, however, is a sufficient reason, without resorting to these explanations.[37] If any other was wanted, it would be found in the early loss of the superior officers. Such a calamity, at the outset of an engagement, will almost invariably turn an even scale. One officer cannot manage a ship, and sailors without leaders never fight well. [Footnote 37: The Pelican was 485 tons, the Argus 298. The former threw nearly two hundred pounds more metal than the latter at every discharge.]
