“Never fear, Roger,” replied Harry. “Cavendish knows what he is about; and I think I see, even now, what manoeuvre he means to execute.”

The three English ships were now heading as though they indeed intended passing between the two lines of the enemy’s squadron, and had so far fired not a single shot. Suddenly, however, when only separated by a few hundred yards, the English changed their course two or three points to port, and headed for the starboard side of the two ships which constituted the right-hand line of the Spanish fleet.

Thus the three English vessels were for a few minutes opposed to only two Spanish ships, the three others being unable to fire except through their consorts.

This manoeuvre compelled the other three ships to leave their present berths and run before the wind, afterwards tacking before they could range up on the opposite side of the English fleet and so bring their guns to bear.

But during the time occupied by this movement, the English ships were by no means idle.

Upon ranging up alongside the two Spanish vessels, the sails of the English ships collapsed as if by magic, the halliards being let go and the clewlines manned; and, as the craft lost way, grapnels were thrown, and the ships were secured alongside two of the Spaniards.

At that period the Spanish war-vessels were built with “flush” decks, that is, their decks were level fore and aft, and without bulwarks, and were of much greater length than the English vessels, which were short, and therefore more easy to manoeuvre than the Spaniards. Likewise there were raised constructions at bow and stern, something like small forts, called forecastles and aftercastles; the former word still remaining under our modern term forecastle.

The English vessels were then, as mentioned above, shorter by a good deal than those of their opponents, and so the total length of the three English ships was covered by that of the two Spanish vessels, which fact preserved them for the moment from the fire of the other three ships of the enemy. Roger now saw the reason why Cavendish had reserved his fire. Immediately his ships came alongside those of the enemy, the broadsides of all three were simultaneously discharged, with fearful effect, for amid the crash of falling spars and rending timbers could be heard the cries and shrieks of the wounded, and the moans of the dying.

A dense cloud of smoke spread over the decks and concealed the combatants from one another, but the din was terrific; while orders and shouts, hoarse words of command, and fierce oaths mingled with the cheers of the English.

The sternmost vessel of the enemy, which was the one that had received the concentrated broadsides of two of the English ships, was now on fire somewhere on her lower-deck; three or four of her ports were blown into one big opening, and her decks were a very shambles of dead and wounded.
