If it appears, as on a bare narrative of the facts it must, that both fleets showed a singular languor during their movements in this summer campaign, it is only fair to take into account the quality of the instruments with which the admirals had to deal. It was not possible to do anything very rapid with clumsy, ill-balanced vessels, which were overstrained by a summer breeze. Moreover, both leaders were in reality hampered by what they no doubt considered an element of strength. The numbers of their fleets alone would have made any kind of combined action impossible. At a time when the vessels were incomparably better, and our seamen had a far larger experience, Nelson considered it impossible to manoeuvre more than thirty ships in a line of battle. That is to say, he thought it beyond the power of the most skilful and practised body of captains ever collected under one command to combine the movements of more than thirty well-constructed ships in such a manner that they could be brought to bear upon an enemy all together. If this was impossible with so small a number of very superior vessels, we can imagine how hopeless must have been the attempt of D'Annebault or Lisle to direct the movements of a hundred and a hundred and fifty inferior vessels of all sorts and sizes. With the best will in the world, they could not but straggle in the variable summer breezes and the tides of the Channel. Besides, the system of signals was hardly yet in existence. There were, and indeed at all times must have been, a few arbitrary signals, to anchor or to get up anchor, to fight or leave off fighting, and so forth, but there were no means by which an admiral could communicate an order to make a particular movement, except by sending a boat with an officer. Of course this implies that the movements of fleets must have been very slow, or else a messenger who had to row could not have overtaken the captain to whom he was sent. Even so, to send orders to the ships ahead of the admiral must have required an amount of time which made any rapidity of movement impossible, besides leaving an interval for accidents which would render the order improper by altering the whole circumstances. In fact, no battle, in the sense the word had in even the seventeenth century, could well be expected to take place between these two fleets in 1545, even if there had been a more manifest desire on the part of the admirals to bring one on.
