Essex was soon trapped against the coast at Lostwithiel. He relied on support from the Parliamentarian navy, but contrary winds prevented the Parliamentarian ships leaving Portsmouth. Although Essex himself escaped in a fishing boat and his cavalry broke out of encirclement, the rest of his army was forced to surrender on 2 September, losing their arms and equipment. The troops were paroled, but suffered severely from exposure and attacks by country people during their march to Portsmouth. Although they were re-equipped, only 3,000 infantry (out of 6,000 who started) were fit for service.
