This Committee taking notice of the arms yt are engraven upon ye sternes of ye shipps belonging to ye Comonwealth & intended for this Summers fleet doe think fit to inform the Comtee of State therewith that so directions may be given what arms shalbe placed in their steed & likewise what characters shalbe given to the flaggs that are to be worne in this service[171].

The Council of State promptly decided "That the Ships at Sea in service of the State shall onely beare the red Crosse in a white flag [172]," thus bringing the navy back to the old English flag and once more into line with the merchant shipping. The royal arms were ordered to be removed from the sterns and replaced by "the Armes of England and Ireland in two Scutcheons[173]."

Two days later the Generals at Sea were informed, in answer to a further inquiry, that if Scots ships were found "bearing either the red cross or the Armes heretofore called the King's Armes" they were to admonish them to "forbeare the carrying of them for the future[174]."

It is probable that the order of 22nd Feb. was not altogether welcome to the navy officers, for on 5th March, only a few days after the above order had been issued, the Council of State decided upon a new union flag for naval use. The union now to be symbolised was that of England and Ireland. Although Ireland had been more or less under the rule of the kings of England from the time of Henry II, it was not until the accession of James I in 1603 that she had found recognition in the royal standard, and it remained for the Commonwealth to give her due recognition in the national flag. The entry in the Council Minute Book runs: "That the fflagg that is to be borne by the Admirall be that now presented, viz: the Armes of England and Ireland in two severall Escotchons in a red flagg wth in a Compartiment (or)[175]."

At the same time two other variants of this design were introduced, a standard and a jack. The order for these cannot be found, but they are referred to in the following letter to the Committee of the Navy signed by Deane and Blake (two of the Generals at Sea[176]) and dated 21st April, 1649:

Gentlemen

Touching the flaggs &c. It seems strange you referre the proportions to bee ascertained by us, yorselves knowing best the former allowaunces, which wee suppose are alike in number in every expedition, but since the Issue depends on or resolution wee think needfull that you make up what you have allready sent, for orselves three Standards, or viceadmll and Rereadmll with the Admll Viceadmll & Rereadmll of Ireland three flaggs apiece, with two Jackes for every Shipp in the ffleet. ffor the Ensignes and pendants you best know how many are wanting, which (whatsoever they are) with the flaggs &c. we desire may bee noe longer delayed[177].

In the standard, intended to replace the royal standard, and to be used by the Generals at Sea, the yellow "compartment" was omitted and the two escutcheons were surrounded by green branches of laurel and bay. Fortunately, an actual specimen[178] has survived of this interesting flag, which was destined to wave over Blake's ship at the heroic battle of Santa Cruz and to see the rise of the English navy to an eminence unequalled even in the days of Elizabeth.

The jack contained only the cross and harp on their white and blue fields, corresponding with the centre part of the Admirals' flags. It is to be seen in several pictures of battles of the First Dutch War[179]. Apparently this jack was also used by ships having letters of marque; "privateers" as we should now call them. In December, 1652, the captain of a small frigate, called the 'Helena,' fought with two armed ships from Brest, "putting out the Parliament Jack on the bowsprit end and the English ensign on the poop, the enemy having hung out the disunion flag or late King's colours[180]."

Early in 1653 the junior Admiral's flag with the red border and yellow compartment seems to have been abandoned, and a flag like the jack, with the harp and cross only, substituted for it[181], probably because the red border would cause confusion when flown in the white and blue squadrons.
