Battle of Brouwershaven

Jaqueline requested support from her husband Humphrey, who was in England, and he set about raising a force of 1500 English troops to reinforce her, led by Walter FitzWalter, 7th Baron FitzWalter. In the meantime, Jaqueline's army had defeated a Burgundian force of city militia at the Battle of Alphen on 22 October 1425. Duke Philip had plenty of notice of the assembly of the English force and raised a fleet to intercept them at sea. Although he did succeed in catching a small part of the English force, consisting of 300 men, most of the English force made landfall at the port of Brouwershaven, where they rendezvoused with their Zeeland allies.

The Zeelander forces allowed their opponents to land unopposed from boats, perhaps hoping for an Agincourt-like triumph with the aid of their English allies.

However, when the Burgundians were still disembarking, the English led an attack, advancing in good order, giving a great shout and blowing trumpets. The English troops were bombarded with a cannonade and a volley of arbalest bolts from the militia. The well-disciplined English longbowmen held firm and then shot back with their longbows, quickly scattering the crossbowmen in disarray. The well-armored and equally disciplined Burgundian knights then advanced and came to grips with the English men-at-arms. Unable to withstand the fierce attack of the knights, the English men-at-arms and archers were driven onto a dike and were virtually wiped out. The loss was devastating to Jacqueline's cause.
