In the 17th century Civil Wars, townspeople of Poulton fought on both sides, although more men from the Fylde were on the side of the Royalists. No battles occurred in or close to Poulton but the area was affected with the rest of the county by the widespread poverty that resulted from the wars. In 1643 interest was stirred in the parish when a large Spanish vessel dropped anchor off the coast at Rossall. The ship made no movement for several days but fired its guns occasionally. Locals initially feared an invasion, but eventually realised that the crew was in distress and had been signalling for help. The vessel was carrying ammunition for the Parliamentarian forces and the crew had become sick and feeble. The ship was brought by Royalists into the mouth of the River Wyre and the Earl of Derby marched from across the River Ribble. He ordered the ship to be burnt and the Spanish crew to be set free.
