The "Mary Rose", a fourth-rate frigate of the English Royal Navy carrying forty-eight guns, conveyed Lord Henry Howard, with an entourage of 70 attendants and £4000 in gifts, to Tangier in 1668 or 1669. The visit was on the order of Charles II to negotiate a commercial treaty with the sultan of Morocco, Al-Rashid, also known as "Tafiletta". The engraver Wenceslaus Hollar formed part of the expedition on his own request to finish drawings of Tangier he had started when he accompanied Howard's grandfather on a similar mission in 1636. The meeting with Mulay Rashid was delayed for eleven months and ended up not taking place at all; then, according to Hollar, Howard obtained a "Letter of Security" from Mulay Rashid and "purposd himself" to "go by Land, and the Ship by Sea to Salee" from where they "set Sail on Wednesday the eighth of the said Month at two a clock in the morning".
