About 4 o’clock in the afternoon of the 2d, Walker marched from San Juan to Virgin Bay. At the latter place he ascertained that Cañas had been there with some four or five hundred men, and had retired as soon as he heard of the approach of the Americans. Early on the morning of the 3d the steamer La Virgen appeared off Virgin Bay, and the troops then in the village were carefully concealed, with the hope that the steamer might come up to the wharf. When, however, she got within a few hundred yards of the wharf, she stopped her engines, yet did not drop anchor, as if regarding the aspect of affairs on shore. After a while several tried to strike her pilot-house with the Minié musket; but their efforts were not very successful; and in a short time the steamer turned away from the wharf and proceeded toward San Jorge. Then the Americans resumed their march and reached Rivas about midday of the 3d. On their return to Rivas the Rifles were ordered to get as much rest as possible during the afternoon and the early part of the night, since their services might be required before daybreak of the 4th. Not long after midnight of the 3d, Walker marched with about 200 of the Rifles toward San Jorge; and near a mile from Rivas, taking a road to the left, he entered the village, where the enemy lay, at 4 o’clock on the morning of the 4th of February. The Allies were taken entirely by surprise, and a select corps of volunteers, led on by Dr. McAllenny, penetrated to one of the main barricades of the Plaza and fired over its top at the enemy, running hither and thither across the square. But the main body could not be brought to sustain the advancing party before the enemy recovered from their surprise. Then it was too late to carry the barricades without great loss, and the Americans were drawn off to the edge of the village beyond the reach of the enemy’s small-arms. During the assault on the barricade Lieutenants Blackman and Gray were mortally wounded; and while the Americans were on the edge of the village O’Neal received his death-wound. By eight o’clock A.M. on the 4th, the Americans had returned to Rivas.
