By May 1428,
Philip the Good had recruited a huge Burgundian army of 20.000 men and raised the siege of Gouda. Gouda was surrounded on three sides, only the river side remained under control of the fleet of
Willem van Brederode. Jacqueline sent messengers to her allies Jan van Montfoort and
Bishop of Utrecht Rudolf van Diepholt, but no help arrived. She could also not count on her English husband
Humphrey, Duke of Gloucester, who had their marriage annulled. After six weeks, and with no help on its way, Jacqueline had no choice but to surrender. She concluded the
Treaty of Delft with Philip the Good of Burgundy on 3 July 1428. By this treaty, hostilities came to an end, Jacqueline retained her titles of Countess of Holland, Zeeland and Hainaut, but she recognized Philip as her heir and regent of her counties. == Sources ==
