. The army was well equipped and had some guns. Burgrave Filips of Wassenaar and the other local Hoekse noblemen assumed that the duke would besiege Leiden first and send small units out to conquer the surrounding citadels. But John of Bavaria chose to attack the citadels first. He rolled the cannons with his army but one too heavy went per ship. By firing at the walls and gates with iron balls the citadels fell one by one. Within a week John of Bavaria conquered the castles of Poelgeest, Ter Does, Hoichmade, de Zijl, ter Waerd, Warmond and de Paddenpoel.

On June 24 the army appeared before the walls of Leiden. On August 17, 1420, after a two-month siege the city surrendered itself to John of Bavaria. The citadel earl Filips of Wassenaar was stripped of his offices and rights and lived out his last years in captivity.

. While the city had lost about a third of its 15000 citizens during the siege of 1574, it quickly recovered to 45000 inhabitants in 1622, and may have come near to 70000 circa 1670. During the Dutch Golden Era, Leiden was the second largest city of Holland, after Amsterdam.

From the late 17th century onwards Leiden slumped, mainly because of decline of the cloth industries. In the beginning of the 19th century the baize manufacture was altogether given up, although industry remained central to Leiden economy. This decline is painted vividly by the fall in population. The population of Leiden had sunk to 30,000 between 1796 and 1811, and in 1904 was 56,044.
