Camber Castle went through several changes at the start of the 17th century. In 1610, Peter Temple was appointed as captain of the castle, and between 1610 and 1614 the garrison was reduced to 14 soldiers, including only 4 gunners, either as an effort to reduce costs or as a result of the changing types of artillery kept at the castle. The north and south bastions were filled in to form solid gun platforms around approximately 1613 and 1615, and an earth rampart called the Rampire was built up against the south corner of the castle. These solid bastions would have sacrificed living space, less in demand with a smaller garrison, but been much cheaper to maintain. Longbows fell out of use in warfare as archery in England declined, and were replaced by arquebuses and muskets, 46 of which were kept at the castle in 1614.
