The English had become used to the king ruling in council, with the advice of his chief men, but Harthacnut had ruled autocratically in Denmark, and he was not willing to change, particularly as he did not fully trust the leading earls. At first he was successful intimidating his subjects, though less so later in his short reign. He doubled the size of the English fleet from sixteen to thirty-two ships, partly so that he had a force capable of dealing with trouble elsewhere in his empire, and to pay for it he severely increased the rate of taxation. The increase coincided with a poor harvest, causing severe hardship. In 1041 two of his tax gatherers were so harsh in dealing with people in and around Worcester that they rioted and killed the tax gatherers. Harthacnut reacted by imposing a then-legal but very unpopular punishment known as 'harrying'. He ordered his earls to burn the town and kill the population. Very few people were killed, however, as they knew what was coming and fled in all directions.
