This battle, one of the most decisive and glorious fought during the war, our author had already celebrated in the verses to the Duchess, immediately preceding this poem; to which, and to the notes, the reader is referred. The famous Dutch admiral Opdam, in his flag-ship, the Eintracht, blew up, while closely engaged with the duke of York in the Royal Charles. Shortly afterwards, four or five Dutch vessels became unmanageable, fell on board of each other, and were all burned by a single fire-ship. Three others were destroyed in the same condition, and by the same means. Two Dutch vice-admirals were killed, whose ships, bearing away, drew many out of the line, so that Van Tromp, who fought gallantly, had, out of a hundred and three ships, only thirty left, to continue a retreating action. This victory was gained on the 3d. June, 1665. Note VII. _And therefore doomed that Lawson should be slain._ St. 20. p. 108. Sir John Lawson, the gallant seaman here mentioned, rose from a mean station in the navy, to be an admiral under the Parliament. He distinguished himself in the Dutch war of 1653, by the incredible damage which the flying squadron he commanded did to the commerce of the States. He entered afterwards into some cabals with the fifth-monarchy-men, a set of pretended saints, who would hear of nothing but a theocracy. It does not appear, whether, on the part of Lawson, this was an alliance of policy or principle; but it cost the admiral an imprisonment under the vigilant administration of Cromwell. He was set at liberty, and declared by the Parliament vice-admiral of the Channel fleet, which he induced by his influence to declare for the Restoration. The admiral was rewarded for this service by the honour of knighthood, and high trust from his sovereign. In the great battle off Loestoff, sir John Lawson met the glorious death which Dryden has here commemorated. He was rear-admiral to the duke of York, and maintained his high character for valour and seaman-ship till late in the action, when he received a musket-shot in the knee, and by its effects was prevented from enjoying the victory, to which he had greatly contributed. He died a few days after the action, in full enjoyment of his country's triumph, and his own glory. Note VIII. _Their chief blown up, in air, not waves, expired, To which his pride presumed to give the law._ St. 22. p. 108. The Dutch occasionally conducted their naval expeditions with great and insolent affectation of superiority. Upon one occasion their admiral sailed with a broom at his main-top-gallant-mast, to signify, he had swept the narrow seas of the English. Opdam, as already mentioned, blew up, while along side of the Duke of York. Some imputed this accident to the revenge of a negro slave; others, to some carelessness in the distribution of the ammunition. Note IX.
