Ada was quickly captured by the supporters of William and taken prisoner in the citadel of
Leiden. She was first imprisoned on the island of
Texel and afterwards she was taken to
John Lackland in the
Kingdom of England. William had to accept Louis and Ada as count and countess at a treaty of
Bruges in 1206. Louis managed to free Ada in 1206, and the couple returned to Loon in 1207. Their reign was short-lived, since Emperor
Otto IV regarded William to have more right to the title Count of Holland in 1208. Ada did not accept the loss of her county, and she and Louis continued the fight. Ada remained childless. Louis died in 1218, leaving Ada to live out the rest of her life in obscurity. She was buried next to her husband in
Herkenrode Abbey. The civil war in Holland became part of a major international war with
France and the
Hohenstaufen dynasty on one side and England and the
Welfs on the other. William could get Holland through good manoeuvring between both sides. Ada and Louis had to give up their claims. Many period histories up to the
Protestant Reformation do not include her in the list of rulers of Holland. ==References==
