Taylor's drawing of a scytheman from two years after Sedgemoor

JOHN TAYLOR’S ACCOUNT OF MONMOUTH’S  REBELLION AND THE BATTLE OF SEDGEMOOR,  6 JULY 1685 edited by John Childs

 John Taylor, a mathematics teacher, enrolled as a gentleman volunteer in the newly-created Queen Consort’s Regiment of Horse on 20 June 1685. Five days later, the unit left London to reinforce the Earl of Feversham’s corps which was operating in Somerset against the Duke of Monmouth’s insurrection. Between 1688 and 1689, Taylor recorded his martial experiences in pp 81–97 of ‘Taylor’s History of His Life and Travels’ (National Library of Jamaica, Kingston, MS 105). This is transcribed below, extensively annotated. Although too late to experience action, Taylor spoke to combatants and visited the Sedgemoor battlefield on 6 or 7 July. This previously unnoticed narrative provides additional detail and some new perspectives on, inter alia, the internal organisation of the rival forces; the identification of Anton Buys; the social activities of royal infantry officers on the night of Sedgemoor; the impact of alcoholic intoxication upon the battle; the tactical roles, equipment, and articulation of Monmouth’s scythemen; and the importance of Tangier veterans.
