On 23 February 1644 a Parliamentary force of three ships arrived in the Haven, and Colonel Rowland Laugharne assumed command of all forces at Pembroke. Two Royalist ships took shelter in the Pill. Parliamentary forces moved canons into position on the eastern side of the Pill in addition to those on ships in the Haven, and a bombardment of the fort began. Land forces arrive from the north of the fort via Steynton, and a truce was called and the fort surrendered. It was manned by Parliamentarian forces for the remainder of the conflict, and dismantled prior to the outbreak of the Second Civil War in 1648. The earth embankments were noticeable until at least the 1930s, but in 1990 the area was bulldozed and is now built over.
