Yes, we had a strong role in the Civil War - Manchester itself being besieged early in the conflict in Sept/Oct 1642. The first English fatality of the conflict was Richard Percival, a Royalist who tried to attack opponants to the Earl Of derby who was attacked when attending a banquet here with his supporters. (The first casualty of the overall conflict was a Scot, David Prat, - at the siege, the Parliament were dominant - Manchester being a Puritan city - Sir Ralph Assheton has a pub named after him in Middleton, there was also a John Middleton - Captain Dukinfield has a statue commemorating his efforts in Dukinfield. The real hero was however a german mercenary, John Rosworm who built the city's earthwork defences and held off the Royalist advances for a week with just a handdful of men.
Royalist Wythenshaw Hall was besieged - a statue of Cromwell stands outside though he was never there - the statue originally stood in the city centre outsidethe Corn exchange - The Earl Of Derby was executed in Bolton for his attack and massacre of the town population there - the pub where he spent his last hours, The Old Man And Scythe, still stands. A Victorian mural depicting the Manchester siege (and full of innacuracies) is in Manchester town Hall and was done by Pre-Raphaelite artist Ford Maddox Brown.
