Of the class of fortified houses erected about this date, a good example is afforded by Greenhalgh Castle. By a royal license granted to Thomas, Earl of Derby, in 1490, he was authorized to erect in Greenhalgh (in the parish of Garstang) a building or buildings with stone or other materials, and to "embattle, turrellate or crenelate, machiolatte," or otherwise fortify the same; authority was at the same time given to enclose a park, and to have in it free warren and chase. Camden says that the Earl built this to protect himself from certain of the nobility of the county whose estates had been forfeited to the Crown and bestowed upon himself. This account of the origin of this castle is probably correct. The great religious changes in Lancashire, brought about by what has been called the anti-Papal revolt, and the subsequent Reformation, will be reserved for a future page (see Chapter IX.). The old strife between England and Scotland had now again been renewed, and the conflict culminated in the battle of Flodden, where the Lancashire archers, led by Sir Edward Stanley, almost totally destroyed the Highlanders who composed the right wing of the Scottish army. The other Lancashire leaders were Sir William Mollineux of Sefton, Sir William Norris of Speke, and Sir Ralph Ashton of Middleton. No wonder that this decisive victory should become a favourite theme of the poet and the minstrel. There are several old poems referring to the Lancashire men and the field of Flodden; one of these, which is certainly 300 years old, has been printed by the Chetham Society;[104] it consists of nearly 700 lines, of which the following will serve as a sample: Lancashire, like lyons layden them aboute! All had been lost by our Lorde! had not these leddes [lads] bene. For the care of the Scottes increased full sore For their King was downe knocked and killed in their sight, Under the banner of a bishop that was the bold Standley! Ther they fetilde[105] them to fly As fast as they might. Another long poem on the same subject is preserved in the Record Office;[106] it gives also a glowing account of how the "lusty lads," led by the "lusty Stanley stout," went forth "in armour bold for battle drest," and how-- From Warton unto Warrington, From Wigan unto Wiresdale, From Weddecon [Wedacre] to Waddington, From Ribchester to Rochdale, From Poulton to Preston, with pikes, They with Stanley out went forth. From Pemberton and Pilling dikes, For battle billmen bold were bent.
