 Warbeck proclaimed that he would put a stop to extortionate taxes levied to help fight a war against Scotland and was warmly welcomed in Cornwall.His wife, Lady Catharine, was left in the safety of St Michael's Mount and when he decided to attack Exeter his supporters declared him ‘Richard IV’ on Bodmin Moor.Most of the Cornish gentry supported Warbeck's cause after their setback previously in June of that year and on 17 September a Cornish army some 6,000 strong entered Exeter, where the walls were badly damaged, before advancing on Taunton.
