Pendennis Castle, however, continued to hold out, defended by around 1,000 soldiers under the command of Sir John Arundell. They were determined to hold out against the besiegers and Arundell announced that he would die rather than surrender. Two Parliamentary colonels, Fortescue and Hammond, directed the bombardment of the castle from the land, while Captain Batten, with a flotilla of ten ships, blockaded it by sea, preventing fresh supplies from arriving. The garrison's defences were supported with artillery fire from a Royalist warship that was deliberately run aground north of the castle to produce an additional gun platform. By July, food had begun to run short and some of the garrison unsuccessfully attempted to break out by sea to acquire supplies. Arundell agreed to an honourable surrender on 15 August, and around 900 survivors left the fort two days later, some terminally ill from malnutrition. Pendennis was the penultimate Royalist fortification to hold out in the war. Parliament maintained a garrison at the castle, but in 1647 it cut the levels of the armed forces across the country; most soldiers who lost their posts were offered two months pay, but at Pendennis only one month's pay was offered. The garrison, led by Colonel Richard Fortescue, mutinied, seized the visiting Parliamentary commissioners and refused to leave the castle until the additional pay was granted to them. Fearing a wider uprising, Parliament negotiated an end to the confrontation, paying off the garrison in full and offering Fortescue fresh employment elsewhere. A smaller, more reliable garrison was then installed. During the interregnum, the castle was used to imprison the radical pamphleteer William Prynne. Just before the restoration of King Charles II to the throne in 1660, the Royalist Sir Peter Killigrew became the new captain of the castle. Fears of an invasion continued, and an additional gun battery was constructed at Crab Quay, to the south-east of the main fortification. At the end of the century, a new guard barracks and gate were constructed, probably emulating those being constructed in France. 18th–19th centuries Pendennis Castle continued in use through the 18th and 19th centuries under the command of successive captains, still operating in partnership with St Mawes. In 1714, Colonel Christian Lilly carried out an inspection of the fortification, finding it to be "in a very precarious condition" and noting that "the body of the fort having been for many years neglected is
