If any fleet shall be discovered at sea which may probably be conjectured to have a purpose to encounter, oppose, or affront the fleet in the Parliament’s service, you may in that case expect more particular directions.  But for the present you are to take notice, that in case of joining battle you are to leave it to the vice-admiral to assail the enemy’s admiral, and to match yourself as equally as you can, to succour the rest of the fleet as cause shall require, not wasting your powder nor shooting afar off, nor till you come side to side.

SUPPLEMENTARY INSTRUCTIONS, circa 1650.

[+Harleian MSS. 1247, 43b.  Draft unsigned+.]

Instructions for the better ordering and managing the fleet in fighting.

1.  Upon discovery of a fleet, receiving a sign from the general’s ship, which is putting abroad the sign made for each ship or frigate, they are to make sail and stand with them so nigh as to gain knowledge what they are and of what quality, how many fireships and others, and what order the fleet is in; which being done the frigates or vessels are to speak together and conclude on the report they are to give, and accordingly report to the general or commander-in-chief of the squadron, and not to engage if the enemy’s ships exceed them in number except it shall appear to them on the place that they have the advantage.

2.  At sight of the said fleet the vice-admiral or he that commands in the second place, and the rear-admiral or he that commands in the third place, are to make what sail they can to come up with the admiral on each wing, as also each ship according to her quality, giving a competent distance from each other if there be sea-room enough.

3.  As soon as they shall [see] the general engage, or [he] shall make a sign by shooting off two guns and putting a red flag on the fore topmast-head, that each ship shall take the best advantage they can to engage with the enemy next unto him.

4.  If any ship shall happen to be over-charged and distressed the next ship or ships are immediately to make towards their relief and assistance upon signal given; which signal shall be, if the admiral, then a pennant in the fore topmast-head; the vice-admiral or commander in the second place, a pennant in the main topmast-head; and the rear-admiral the like.

5.  In case any ship shall be distressed or disabled by loss of masts, shot under water, or otherwise so as she is in danger of sinking or taking, he or they are to give a signal thereof so as, the fleet having knowledge, they may be ready to be relieved.  Therefore the flagships are to have a special care to them, that such provisions may be made that they may not be left in distress to the mercy of the enemy; and the signal is to be a weft[1] of the ensign of the ship so distressed.
