"A 'large cannon ball found in Carew Castle' was exhibited at Tenby in 1851 to the Cambrian Archaeological Association by the Rev. G. N. Smith, then vicar of Gumfreston. At the same meeting Mr. Nicholas Roch exhibited 'two small cannon balls, ploughed up in a field at Paskeston, within range of Carew Castle' (Arch. Camb., 1851, II, ii, 385). The above were doubtless relics of the assault upon the medieval castle in 1644." Source: RCAHMW, Pembrokeshire Inventory, 1925, i, no.129.
Rowland Laugharne's parliamentary force took Carew Castle during the Civil War in 1644; the site of the skirmish is believed to be Carew Meadows, just to the south of the castle.
