Revolt in the West - the western rebellion of 1549 John Sturt
I've finished reading this slight book and very interesting it was too. Well worth the £1.47 that it coats on Amazon. Some interesting things I learnt - Cornish tin miners nearly succeeded in mining one of the strongpoints in the siege of Exeter. Also 900 prisoners had their throats cut by the Royalists. In short get this booklet. It's a worthwhile read.
