Wiseman learned surgery on the battlefield. The royalist army was then under the command of
Ralph Hopton, 1st Baron Hopton. After the defeat at Truro, on his own account, Wiseman was the only surgeon who continuously attended Charles, the Prince of Wales, from the west of England to France, Holland, and Scotland, in the years 1646–1650. He was at first attached to the troops in attendance on the prince, but when Surgeon Richard Pile (Pyle) returned to England he became the prince's immediate medical attendant. Wiseman accompanied Prince Charles from Jersey to France, and from France to The Hague, where news arrived in February 1649 of the
execution of Charles I. From The Hague Wiseman accompanied Charles II to
Breda, Flanders and back to France, arriving at
St. Germains in August 1649. He then went to Jersey again, and when Charles left Holland in June 1650 Wiseman accompanied him to Scotland. He was taken prisoner at the
battle of Worcester (3 September 1651) and marched to
Chester, where he was kept in captivity. Having procured a pass, Wiseman arrived in London about February 1652, and was admitted to the Company of Barbers and Surgeons of London, 23 March 1652. He acted for a time as assistant to
Edward Molines of
St. Thomas's Hospital. Then he set up in practice for himself, living in the
Old Bailey at the sign of the King's Head, where he had royalist patients. Early in 1654 he was rearrested on a charge of assisting Read, a patient, to escape from the
Tower of London, and in March 1654 he was sent a prisoner to
Lambeth House. It appears that he owed his liberty to friends. Wiseman wrote that he served for three years in the Spanish navy, and from the evidence it has been deduced that this period was from 1654 to 1657. He was in
Dunkirk, then a Spanish possession, and the Caribbean. ==Later life, death and legacy==
