De la Hay, being over-confident because of his superior numbers, blundered at the outset. Instead of attacking first with his infantry, he placed his horsemen in front, and ordered an assault. Cavalier was quick to take advantage of this blunder. He ordered only a few of his men to fire, and this drew a volley from the advancing horsemen, which did little damage to the sheltered troops, but emptied the horsemen's weapons. Instantly Cavalier ordered a charge and a volley, and the horsemen, with empty pistols, gave way, Cavalier pursuing them. De la Hay's infantry, being just behind the horsemen, were ridden down by their own friends, and became confused and panic-stricken. Cavalier pursued hotly, his men throwing off their coats to lighten themselves, and giving the enemy no time to rally. A reinforcement two hundred strong, coming up, tried to check Cavalier's charge; but so impetuous was the onset that those fresh troops gave way in their turn, and the chase ended only when the king's men had shut themselves up in the fortified towns. Cavalier had lost only five or six men, the enemy losing a hundred killed and many more wounded. Cavalier captured a large quantity of arms and ammunition, of which he was in sore need. When the battle was over it was decided unanimously to make Cavalier the commander. He refused, however, to accept the responsibility unless it could be accompanied with power to enforce obedience, and his troops at once voted to make his authority absolute, even to the decision of questions of life and death. According to the best authorities, Cavalier was only seventeen years old when this absolute command was conferred upon him. How skilfully he used the scant means at his disposal we shall see hereafter. On one occasion Cavalier attacked a party of forty men who were marching through the country to reinforce a distant post, and killed most of them. While searching the dead bodies, he found in the pocket of the commanding officer an order signed by Count Broglio, the king's lieutenant, directing all military officers and town authorities to lodge and feed the party on their march. No sooner had the boy soldier read this paper than he resolved to turn it to his own advantage in a daring and dangerous way. The castle of Servas, near Alais, had long been a source of trouble to him. It was a strong place, built upon a steep hill, and was so difficult of approach that it would have been madness to try to take it by force. This castle stood right in the line of Cavalier's communications with his friends, near a road which he was frequently obliged to pass, and its presence there was a source of annoyance and danger to him. Moreover, its garrison of about forty men were constantly plundering and murdering Cavalier's friends in the country round about, and giving timely notice to his enemies of his own military movements.
