Close by, their fire-ships, like jackals, appear,
Who on their lions for the prey attend.
St. 82. [p. 119.]
Fire-ships, now only employed against fleets in harbour, and seldom even then, were at this time used during every great naval engagement. The Dutch wars, especially, were distinguished by the frequent use of these dreadful engines of destruction on both sides. The last instance, I believe, of their being employed in open sea in the British service, occurred in the engagement of Matthews and Lestock in the Mediterranean, where they did little execution. The reason of their disuse appears to be, that modern fleets consist of a few large vessels, which easily communicate by signal, and are little apt to fall into such confusion as that fire-ships can approach them with safety, and with any chance of effect. In the 17th century, fleets consisted of a very great number of comparatively small vessels, sometimes a hundred and upwards, which, from the imperfect nature of their signals, were perpetually getting into disorder, and affording opportunities for the fire-ships to act with all their fearful consequences. In the battle of Southwold Bay, in 1672, the gallant Earl of Sandwich, in his fine ship the Royal James, after sinking three fire-ships, was burned by a fourth; and the contest of the Harry with three fire-ships, in this very battle, will be found in a subsequent note.
He drew his mighty frigates all before,
On which the foe his fruitless force employs:
His weak ones deep into his rear he bore,
