William Sumpner, seized part of the magazine in the town of Preston, conveying it away secretly on packhorses as ordinary merchandise. The magazine, which consisted of 13 barrels of powder and some match, had been mostly collected by Farington and stored in a private house. Early next morning the remainder was removed by order of the Sheriff. Rigby hearing of what had taken place again protested, but to no purpose; and he was not in a position to use force.[11] This was part of a royalist plan for securing all the ammunition in the county. Considerable stores had been established by Lord Strange when Lord Lieutenant, the principal centres being Preston, Warrington, Liverpool and Manchester. Warrington was royalist in sympathy and that also was seized by the King. Strange in person secured most if not all of the powder at Liverpool. Rigby, however, warned Mr. Assheton of Middleton in time to save the magazine at Manchester.[12] When the royalist design became known in Manchester a petition was addressed to the Committee asking them if necessary to remove the magazine to a more secure place. The answer refers to great levies of money made by Lord Strange, much of which had been spent in providing ammunition in various places. But there were in Manchester only 10 barrels of powder and a few bundles of match; they were kept in the then disused College of the Church which had been granted to the Earl of Derby by the Crown. This building was afterwards purchased by the executors of Humphrey Chetham from Charles, eighth Earl of Derby, and is still the Chetham College. The royalist Commissioners of Array, Sir Alexander Radcliffe and Mr. Prestwich, with Mr. Nicholas Mosley and Thomas Danson, the Under Sheriff, endeavoured to seize these stores as they had seized the others; but Assheton and Sir Thomas Stanley, another Deputy Lieutenant, prevented them. Judging, however, that the powder was not safe on Lord Strange's property, it was removed to other parts of the town.[13] Lord Strange was very angry at the rebuff and threatened to attack the town. He collected troops at Bury and more than 1000 armed volunteers came in for the defence of Manchester. These outnumbered the royalists, and negotiations were thereupon entered into for the disposal of the magazine. Two or three Deputy Lieutenants visited Lord Strange at Bury; but his offer to replace the magazine in the College in the joint keeping of the Parliament men and of Robert Holt, one of his own Deputy Lieutenants, was refused. (June 23.) Next day the forces were dismissed; but Lord Strange, having received fresh instructions from York, called a second muster at Bury and caused an order to be published at Manchester Cross for the removal of the magazine, part to Rochdale and part to Bury, only a small part to be left in Manchester.
