Battle of Picotin

The subsequent events are described in the Aragonese version of the Chronicle of the Morea. In late 1315, Princess Matilda arrived in Achaea, landing at Port-de-Jonc with 1,000 Burgundian soldiers, as her husband's vanguard. Nicholas le Maure and several of the Achaean barons, who had recognized Ferdinand's rule, now came over to seek her pardon. Ferdinand reacted by capturing the castle of Chalandritsa, whose baron had defected to Matilda, and garrisoning it with 1,500 men. He then proceeded to lay siege to Patras, which was successfully defended by its archbishop, Renier.^[7][8][9]

In early 1316 the Princess appointed a commander, who led the Burgundians and the feudal levies of the Achaean barons loyal to her north. The loyalist army encamped at a village called Picotin, near Palaiopolis (ancient Elis), and on 22 February Ferdinand marched out from Andravida to meet them with 500 cavalry and 500 Almogavar infantry. According to the Chronicle, to speed their progress, Ferdinand ordered his riders to take each one of the infantry on their horses, himself giving the example. When he saw the Catalans approaching, the Princess' captain arranged the 700 Burgundians in the front line and charged the advancing Catalan army, leaving the Achaean troops back in the second line. The Burgundians unhorsed 300 Catalans on the first clash, but the dismounted riders, together with the Almogavars, used their lances to kill the Burgundian knights' horses to terrible effect: within less than two hours, according to the Chronicle, the Catalans killed 500 Burgundians and 700 native troops, including Gilbert Sanudo, brother of the Duke of Naxos, and many other nobles. The Catalans reportedly counted 700 dead horses on the battlefield. The remnants of the Princess' army withdrew in haste, pursued by the Catalans for a while, before they turned back to loot the abandoned Achaean camp.^[7][8][10]

At about the same time as the battle at Picotin, an attempt by Renier of Patras and his men to capture Chalandritsa, while Ferdinand was pre-occupied with the princely army, failed.^[8][11] The defeated Achaean barons retreated once more to the south, into Messenia. There they were soon joined by Louis and his main force, who had landed in Greece at about the time of the battle. Reinforced by Byzantine troops from Mystras, Louis enjoyed a large numerical superiority, and at the Battle of Manolada on 5 July 1316, Ferdinand was defeated and killed. The Catalans abandoned the fortresses they controlled and left Achaea a few months later.^[12][13]
