The fortress on the island of Inchgarvie was captured and destroyed by Richard Brooke in the "Galley Subtile" on 6 May. Hertford had mentioned in his dispatch that it would have been useful to garrison Inchgarvie, but his orders from Henry VIII would not allow it. Christopher Morris shipped the larger artillery, the ships sailed, and on 14 May the harbour and piers of Leith were demolished. Hertford, as the King's Lieutenant, knighted fifty-eight of his captains and his servant Thomas Fisher distributed three pounds and fifteen shillings amongst the men. The army left Leith by land on 15 May, stopping to burn Seton Palace and Haddington. Although Hertford's army entered the town with little resistance, the defenders of the castle led by the Captain, James Hamilton of Stenhouse kept up an artillery barrage, firing down the line of the Royal Mile. The Clerk of the King's Works, Richard Lee, who was Captain of the Pioneers on this expedition and the Surveyor of Calais, William Burgate, declared the castle impregnable. One of the Castle gunners was Andrew Mansioun, a French carver who had made fittings for the "Unicorn", the yacht of James V and furniture for the royal palaces. His hand was injured when a cannon backfired, and in June 1544 he was given 44 shillings to pay for treatment. Repairs were made in July 1544, when two of the gunners, Tibault Roqueneau and Piers Schouffene (French or Flemish, originally employed at Dunbar Castle) were working to improve the gun emplacements with gabions. The fore-wall of the castle was strengthened and repaired from July. This work was completed between July and August 1546 by three masons and four workmen (called barrowmen in the accounts). Hertford estimated the value of goods in Leith at £10,000. This included a large stock of three grades of linen cloth from Brittany. The ships were loaded with property seized in Edinburgh and Leith. He also took the "Salamander" and "Unicorn", loading them with 80,000 cannon balls for ballast from the King's Wark arsenal. One surviving captured item is the Dunkeld Lectern, removed from Holyrood Abbey before the English soldiers fired the church. The lectern may have come into the possession of Sir Richard Lee who made plans of Edinburgh and Leith and assessed the strength of Edinburgh Castle.
