A bilingual (English and Norman French) royal writ from King Edward II ordering the bailiffs and prudent men of Bristol, Portsmouth, Weymouth, Lymington, Warham, Lyme, Melcombe, and Poole to dispatch a well-manned navy to the Isle of Man by Assumption Day (15 August 1310), thence to Scotland under Admiral Simon de Montagu to conduct military operations against Scottish forces. The document demonstrates the strategic importance of the Isle of Man as a naval staging post in medieval Anglo-Scottish conflicts.
