Further confirmation of its use is given by the medals issued in 1665 by Charles II., which he granted to his followers in recognition of service. One of these is given in fig. 21. On the reverse is a ship in full sail. On the flag at the mainmast head are the letters "C.R.," being the abbreviation of CAROLUS REX, and intended to indicate that the flag was the Royal Standard; at the bow the two-crossed Jack, and at the stern the Red Ensign with the St. George Jack in the upper corner. The place of distinction at the stern had been occupied, as under Charles I., by the Royal Standard of the reigning kings. To this position the Commonwealth ensign had been installed as being the ensign of the State, and then by the unpremeditated transition at the "Restoration" the Red Ensign succeeded to the post of honour as the ensign of the nation. The story of this flag again exemplifies its harmony with the peculiar genius of the British constitution, for it attained to its position, not by a single verbal enactment, but by force of unwritten usage, and its gradual acceptance by the will of the people, after which it was confirmed by the Act of the sovereign. It will also be noted in the drawing of the _Naseby_, and on the medal, that the Royal Standard of Charles II. is shown flying at the main. This was the position at which it had, under previous sovereigns, been displayed by the Lord High Admiral of the Navy to indicate his rank. The Earl of Warwick, who was Lord High Admiral under Charles I., continued to fly it at the main even after the death of the King; but when Warwick was dismissed from his post by the Commonwealth, the Royal Standard was no longer used as the distinction flag of the Royal High Admiral. When the Commonwealth ended and a new King returned, it was again raised to the place where it had been displayed by the last Royalist admiral. At the present day the Royal Standard, being the personal flag of the Sovereign, is only shown to indicate the royal presence or that of some member of the Royal Family, or raised in recognition of some special royal day. On shipboard it is raised on the mainmast immediately the royal personages come alongside, and is lowered the moment that they leave, the national ensign being still displayed at the stern. It was the St. George cross which had been placed in the upper corner of the Commonwealth ensign; from here it had passed into the Ensign Red of Charles II., thereafter borne at the stern on both merchantmen and men-of-war. In the paramount ensign of the nation the single-cross English Jack was thus carried from 1648 to 1707, when its place in the national ensign was taken for the first time by a two-crossed Jack, and then only by the first _real_ Union Jack, the Jack of Queen Anne.
