Flowers of History. 1069. Between the time of the two festivals of the blessed Virgin Mary, in the autumn, the two sons of Sweyn (age 50) [King Harald III of Denmark (age 29) and King Canute "The Holy" IV of Denmark (age 27)] came with three hundred ships from Denmark into England, in order to subdue it in a hostile manner, and to take king William prisoner (age 41), or else expel him from England. But when their arrival was noised abroad, the counts, and barons, and nobles of the land went forth to meet them, being oppressed by the intolerable arrogance of the Normans; and they made a treaty with them, and so joined the army of the Danes, in order to overthrow king William (age 41). But William (age 41), that most prudent king, when he saw the danger that threatened him, humbled himself to them, and checked the insolence of the Normans; and having in this way recalled many of the English nobles to their allegiance, and having sagaciously made a treaty with them all, he took the city of York [Map] by storm, which was a great rendezvous of the Danes, and made himself master of every thing in it, and slew many thousand men there.

In 1069 King Sweyn II of Denmark (age 50) sent an army to England to attack King William "Conqueror" I of England (age 41) in support of Edgar Ætheling II King England (age 18). Sveyn's (age 50) army captured York [Map] and were then bought off.
