 In the following March Morris was serving at Tournai, but soon returned to his post at the Tower, where he apparently remained until the summer of 1522.He was on board one of the vessels which, under Thomas Howard, Earl of Surrey's command, escorted Charles V to Biscay after his visit to England in 1522; in July a detachment with artillery was landed on the coast of France near Morlaix, which was captured, "for the master gunner, Christopher Morris, having certain falcons, with the shot of one of them struck the lock of the wicket in the gate, so that it flew open," and the town was taken.In August 1523 Morris was acting as lieutenant-gunner before Calais, and on the 23rd of that month he sailed with the vice-admiral, Sir William Fitzwilliam (later Earl of Southampton), and landed near Treport; after severe fighting they re-embarked, burning seven ships and capturing twenty-seven pieces of ordnance.
