Henry VIII wanted glory. He wished to renew the Hundred Years War with France.
In 1422 Henry VI of England had been proclaimed king of France; by 1453 the English had been expelled from France, except for the port of Calais. Henry wished to reassert his claim to the throne of France.
Within weeks of his accession, Henry married Catherine of Aragon in order to renew England’s alliance with Spain. Spain might be the ally England needed.
Wolsey organized the expedition.
Henry led 30,000 men and captured the towns of Therouanne and Tournai.
The French were forced to flee after a skirmish known as the Battle of the Spurs.
