There was, however, some distinction by which the presence of the king could be denoted, and this difference lay most probably in the position of the standard. We know that the "banner of council" placed in the shrouds as a signal to call the council to the flagship, which is the earliest signal recorded as used in the English fleet, dates from this period, and that it contained the royal arms, with angelic supporters, or impaled with the cross of St George, and that from the sixteenth to the eighteenth century this "banner" was the royal standard[222]. But the most prominent position for a flag worn in a ship is at the masthead, and it would seem that it was this position of the standard that was reserved for the king or his deputy, the Lord Admiral. When Edward III led the English fleet to the attack on the French fleet at Sluys in June, 1340, his ship was decorated with banners and streamers containing the new royal arms, and had a silver-gilt crown at the masthead. Li rois estoit en un vassiel moult fort et moult biel qui avoit esté fais, ouvrés et carpentés a Zandwich et estoit armés et parés de banières et d'estramières très rices, ouvrées et armoiies des armes de France et d'Engleterre esquartelées; et sus le mast amont avoit une grande couronne d'argent dorée d'or qui resplondisoit et flambioit contre le soleil[223]. It was, however, not the gilt crown but the flags that denoted the king's presence, for Froissart explains that it was by these flags that the French knew the king was himself present. "Bien veoient entre yaus[224] li Normant par les banières que li rois d'Engleterre y estoit personelment[225]." In 1495, when Henry VII was encouraging John Cabot and his sons in their voyages of discovery, he granted them the right to fly the royal banners and flags: "plenam ac liberam authoritatem, facultatem et potestatem navigandi ad omnes partes ... sub banneris, vexillis, et insigniis nostris[226]," presumably in the same way as they were flown on the royal ships. The earliest surviving orders directing the Lord High Admiral to fly the royal standard at the masthead are those of 1545, at the end of Henry VIII's reign. "Item the Lord Admiral shall beare one banner of the Kings Maj^{ts} Arms in his mayne topp and one flag of saint George crosse in his foretopp[227]." The royal standard was flown at the main, with the St George at the fore, by Howard during the Armada fights in 1588 and during the Cadiz Expedition of 1596. In 1618, by arrangement with the Marquis (afterwards Duke) of Buckingham, Howard (then Earl of Nottingham) resigned the office, which was transferred to the Marquis. Buckingham made his first appearance at sea as Lord High Admiral when he accompanied Prince Charles on his return from Spain in 1623. For this voyage, a not inconsiderable sum of money was expended in flags, which included:
