Despite the animosity between the King and Parliament, there remained an illusion that the two sides were still governing the country together. This illusion ended when Charles moved to York in mid-March, fearing that he would be captured if he remained in the south of England. The first open conflict between the two sides occurred at Kingston-upon-Hull, where a large arsenal housed arms and equipment collected for the earlier Bishops' Wars. During the first Siege of Hull in 1642, Charles was refused entrance into the city in April and again in July by the Parliamentarian governor. Charles was successful in raising men to the Royalist cause in the north of England, the East Midlands and Wales, but without control of a significant arsenal, he lacked the means to arm them. In contrast, Parliament drew troops from the south-east of England, had plentiful arms, and controlled the navy.
