It was only of late that this fine body of men had been organised and received the name of marines, their duty being especially to serve on board ships. They were under command of the Prince of Hesse. His Highness, having taken post on the isthmus, summoned the governor to surrender, but that brave officer returned an answer, that he would defend the place to the last. On the 22nd, the admiral, at break of day, gave orders that the ships which had been appointed to cannonade the town, under the command of Rear-Admiral Byng and Rear-Admiral Vanderdosen, as also those which were to batter the South Mole Head, commanded by Captain Hicks of the "Weymouth," should arrange themselves accordingly. The wind, however, blowing contrary, they could not get into their places till the day was well-nigh spent. In the meantime, to amuse the enemy, Captain Whitaker was sent in with some boats, and a French privateer of twelve guns was burned at the Old Mole. On the 23rd, soon after break of day, the ships being all placed in their stations, the admiral gave the signal for beginning the cannonade; and now the guns opened with a furious fire. The shot, like hail, flew against the Spanish batteries. The British seamen firing as fast as they could load, in five or six hours upwards of fifteen thousand shot were calculated to have been discharged against the town, and the enemy were driven from their guns, especially at the South Mole Head. Seeing this, the admiral sent an order to Captain Whitaker to attack the town with all the boats of the fleet. In the meantime, however, Captain Jumper, who saw what was necessary to be done, and Captain Hicks, who both lay next the Mole, had pushed on shore with their pinnaces and some other boats before the rest could come up. John Deane and two other lieutenants accompanied their captain. They, rushing forward as British seamen always will do when led by their officers, took possession of the fort with great bravery, but not without sustaining a considerable loss. As they, with swords and pistols in their hands, were rushing on, suddenly a fearful noise was heard. The earth seemed to lift up beneath their feet, and forty men and two lieutenants were carried up, fearfully burned and shattered. The survivors, among whom was John Deane, undaunted by this disaster, fought their way on and took possession of the grand platform, where they remained until reinforced by a body of seamen who had come in the boats under Captain Whitaker. The whole body then advanced and took a redoubt half-way between the Mole and the town, possessing themselves also of many of the enemy's cannon. The admiral then sent in a letter to the governor, and at the same time a message to the Prince of Hesse, directing him to send a peremptory summons, which His Highness accordingly did.
