He thought so well about it, however, that when all preparations had been made, to the very great disgust of the older officers of the ship, he detailed Maurice to the command of the party. On account of his lack of rank, his junior officers were all midshipmen. He and the four midshipmen and one hundred and twenty men and boys, including some of the best seamen, composed the landing party, with four months' supply of provisions and ammunition. As the _Centaur_ got under way and beat up toward Fort Royal, Maurice tore open an envelope the commodore had handed him when he bade him good-by. It was a commission and orders to command H. B. M.'s sloop-of-war _Diamond Rock_, five guns and one hundred and twenty men! He almost fell over the precipice in surprise and delight at the situation. The rock was entirely barren except on the north-west side, where a little depression existed in which there was a group of stunted wild fig-trees. There were two or three caves half-way up to the summit, dry and airy, the floors covered with fine sand, of which the officers chose the smallest, the men another, and all hands made themselves very much at home. The crew was divided into watches, a station bill made out, lookouts appointed, and the regular routine of a man-of-war begun. They had not long to wait to demonstrate their usefulness. Two days after the departure of the _Centaur_ the lookout on the top of the rock saw a frigate under a tremendous press of canvas endeavoring to run between the rock and the shore and make for Fort Royal. Far away, and coming along like a gigantic white cloud, was a ship which was presently made out to be the _Centaur_. A drummer-boy, not the least important member of the crew of the _Diamond Rock_, beat to quarters, the men sprang to their stations, and the huge guns were loaded and carefully trained on the unsuspicious French ship. She came booming along at a terrific pace. Maurice, with a coolness remarkable in one so young, waited until she was well in range, and then, taking careful aim, with the long twenty-four half-way up the summit, ignited the priming.
