They had the reputation of being two of the hardest fighters alive, and both were convinced of their power of sweeping the Dutch from the sea by sheer hard hitting, a belief which so far at least as Monck was concerned the country enthusiastically shared.

For the knowledge of these remarkable orders, which go far to solve the mystery that has clouded the subject, we are again indebted to Lord Dartmouth.

They are entered like the others in Sir Edward Spragge's 'Sea Book.' They bear no date, but as they are signed 'Rupert' and addressed to 'Sir Edward Spragge, Knt., Vice-Admiral of the Blue,' we can with certainty fix them to this time.
