The Huguenot forces left by
Admiral Coligny to defend the area where Tavannes crossed were negligent in their duties and did not detect the Catholic forces until the majority had passed over. Coligny now had to concentrate his dispersed forces in the face of this unexpected thrust. He brought as many of these as he could find to the villages of Bassac and Triac, which lay to the west of the marshy Guirlande stream. Around 11:00 a.m., the Catholic vanguard under
Louis, Duke of Montpensier, consisting in total of 4,000 horse and 7,000 foot, attacked Coligny's position along the Guirlande. This was defended by Huguenot
arquebusiers. Montpensier engaged these with 1,200 arquebusiers drawn from his own veteran infantry regiments while 500 of his cavalry sought a crossing further upstream. The Catholic infantry pushed the Huguenots back, forcing them retreat to the village of Bassac. To cover this movement, Huguenot cavalry were dispatched to aid them. However, the Royalist avant-garde cavalry had found a crossing and wheeled down against their left flank. The Huguenot horse were scattered towards Triac. The southern end of this position, next to the Charente, was covered by a large pond and a narrow valley. It was covered by a force of Coligny's arquebusiers. The difficulty of negotiating these obstacles temporarily deterred the Catholic advance. Having received the Admiral's request for assistance, Condé marched towards the battle. He gathered up his cavalry as he did so and arrived by Tirac at 1:00 p.m By this time the
Henry, Duke of Anjou had come up with the main battle and Tavannes realised that the ground north of the pond was suitable to resume the advance. Montpensier's vanguard cavalry moved first. They were followed by the battle. The southern end of this formation, nearest the Charente, consisted of the Catholic reiters. The Catholic guns fired a couple of salvoes before the cavalry moved forward to attack at about 2:00 p.m. The Huguenots countered by attacking with both the left and right wings of cavalry, but these jaded horsemen gave way before Montpensier's more numerous cavalry. At this point the Prince threw himself and his followers into the midst of the Catholic forces, turning back the vanguard cavalry and driving into Anjou's own horsemen. But gallant though the charge was, it was doomed to failure. The scattered Huguenot horsemen could make no impression on the Catholic foot. The Catholic reiters managed to force their way past the infantry guarding the road that linked Brassac to Tirac. From this position, they were able to fall on Condé's flank. Condé was dismounted, many Huguenot gentlemen falling around him. Despite being unarmed and under guard, the Prince was executed, possibly by a Gascon named Montesquiou, and his corpse was paraded in Jarnac to the jeers of the local populace. Minor participants on the Huguenot side were the English volunteer
Walter Raleigh and
Louis of Nassau. ==Aftermath==
