You shall favour your topmasts and the head of your mainmast by bearing indifferent sail, especially in foul weather and in a head sea and when your ship goeth by the wind; lest, by the loss of a mast upon a needless adventure, the service is deprived of your help when there is greatest cause to use it.

The whole fleet is to be divided into three squadrons: the admiral's squadron to wear red flags and red pennants on the main topmast-head; the vice-admiral's squadron to wear blue flags and blue pennants on the fore topmast-heads; the rear-admiral's squadron to wear white flags and white pennants on the mizen topmast-heads.[2] 18.

The admirals and officers are to speak with me twice a day, morning and evening, to receive my directions and commands, which the rest of the ships are duly to perform.

If I be ahead I will stay for them, if to leeward I will bear up to them.

If foul weather should happen, you are not to come too near me or any other ship to hazard any danger at all.
