It was a bold departure from the absolute rule laid down in the "Fighting Instructions," still new, though warranted by the more formal example of Howe on 1 June 1794; and on this occasion, as on the former, was crowned with complete success. The engagement was long and bloody; for though Duncan, by passing through the enemy's line, had prevented their untimely retreat, he had not advanced further in tactical science, and the battle was fought out on the primitive principles of ship against ship, the advantage remaining with those who were the better trained to the great gun exercise, though the Dutch inflicted great loss on the Royal navy.
