In April 1642, Sir John Hotham denied King Charles I entry to the fortified port of Kingston upon Hull, which was under Parliament's control and held a significant arsenal. This refusal marked a critical moment as the Royalists later attempted to besiege Hull in 1643, but their efforts were thwarted by strong defenses and adverse conditions, leading to their retreat. Hull remained a crucial stronghold for Parliament in Yorkshire.

The events surrounding the sieges of Hull became emblematic of the struggle between royal authority and parliamentary power. Hotham's initial rejection of the king was portrayed in pamphlets as both a heroic stand and an act of treachery, while the successful defense in 1643 fostered narratives of civic endurance and communal heroism, expanding the scope of heroic literature beyond traditional aristocratic figures.
