Amongst the more important retentions of tactical signals we find that for Hoste's method of giving battle to a numerically superior force by leaving gaps in your own line between van, centre and rear. The wording however is changed. It is no longer enjoined as a means of avoiding being doubled. As Howe inserted it in MS. the signification now ran 'for the van or particular divisions to engage the headmost of the enemy's van, the rear the sternmost of the enemy's rear, and the centre the centre of the enemy. But with exception of the flag officers of the fleet who should engage those of the enemy respectively in preference.'[8] This signification again is considerably modified by the Explanatory Instructions. Article XXIV., it will be seen, says nothing of engaging the centre or of leaving regular gaps. The leading ship is to engage the enemy's leading ship, and the rearmost the rearmost, while the rest are to select the largest ships they can get at, and leave the weaker ones alone till the stronger are disabled. It was in effect the adoption of Hoste's fifth rule for engaging a numerically superior fleet instead of his first, and it is a plan which he condemns except in the case of your being individually superior to your enemy, as indeed the English gunnery usually made them.

The curious signal No. 218 of 1782 for attacking the enemy's rear in succession by 'defiling' on the Elizabethan plan was also retained. In the Signal Book of 1799 it ran, 'to fire in succession upon the sternmost ships of the enemy, then tack or wear and take station in rear of the squadron or division specified (if a part of the fleet is so appointed) until otherwise directed.'

It has been already said that the alterations in the edition of 1799 were not of great importance, but one or two additions must be noticed. The most noteworthy is a new signal for carrying out the important rule of Article IX. of the Instructions of 1782 (Article X. of 1799), providing for the formation of a corps de réserve when you are numerically superior to the enemy, as was done by Villeneuve on Gravina's advice in 1805, although fortunately for Nelson it was not put in practice at Trafalgar.

The other addition appears in MS. at the end of the printed signals. It runs as follows: 'When at anchor in line of battle to let go a bower anchor under foot, and pass a stout hawser from one ship to another, beginning at the weathermost ship,' an addition which would seem to have been suggested by what had recently occurred at the Nile. Nelson's own order was as follows: 'General Memorandum.—As the wind will probably blow along shore, when it is deemed necessary to anchor and engage the enemy at their anchorage it is recommended to each line-of-battle ship of the squadron to prepare to anchor with the sheet cable in abaft and springs, &c.'[9] Another copy of the signal book has a similar MS. addition to the signal 'Prepare for battle and for anchoring with springs, &c.'[10] It runs thus: 'A bower is to be unbent, and passed through the stern port and bent to the anchor, leaving that anchor hanging by the stopper only.—Lord Nelson, St. George, 26 March, 1801. If with a red pennant over with a spring only.—Commander-in-chiefs Order Book, 27 March, 1801.' These therefore were additions made immediately before the attack on the Danish fleet at Copenhagen.

No other change was made, and it may be said that Howe's new method of breaking the line was the last word on the form of attack for a sailing fleet. How far its full intention and possibilities were understood at first is doubtful. The accounts of the naval actions that followed show no lively appreciation on the part of the bulk of British captains. On the First of June the new signal for breaking through the line at all points was the first Howe made, and it was followed as soon as the moment for action arrived by that 'for each ship to steer for, independently of each other, and engage respectively the ship opposed in situation to them in the enemy's line.' The result was an action along the whole line, during which Howe himself at the earliest opportunity passed through the enemy's line and engaged on the other side, though as a whole the fleet neglected to follow either his signal or his example.

In the next great action, that of St. Vincent, the circumstances were not suitable for the new manoeuvre, seeing that the Spaniards had not formed line. Jervis had surprised the enemy in disorder on a hazy morning after a change of wind, and this was precisely the 'not very probable case' which Clerk of Eldin had instanced as justifying a perpendicular attack. Whether or not Jervis had Clerk's instance in his mind, he certainly did deliver a perpendicular attack. The signal with which he opened, according to the signification as given in the flagship's log, was 'The admiral intends to pass through the enemy's line.'[11] There is nothing to show whether this meant Howe's manoeuvre or Rodney's, for we do not know whether at this time the instruction existed which enabled the two movements to be distinguished by a pennant over.

What followed however was that the fleet passed between the two separated Spanish squadrons in line ahead as Clerk advised. The next thing to do, according to Clerk, was for the British fleet to wear or tack together, but instead of doing so Jervis signalled to tack in succession, and then repeated the signal to pass through the enemy's line although it was still unformed. It was at this moment that Nelson made his famous independent movement that saved the situation, and what he did was in effect as though Jervis had made the signal to tack together as Clerk enjoined. Thereupon Jervis, with the intention apparently of annulling his last order to pass through the line, made the signal, which seems to have been the only one which the captains of those days believed in—viz. to take suitable stations for mutual support and engage the enemy on arriving up with them in succession. In practice it was little more than a frank relapse to the methods of the early Commonwealth, and it was this signal and not that for breaking the line which made the action general.

Again, at the battle of Camperdown, Duncan, while trying to form single line from two columns of sailing, began with the signal for each ship to steer independently for her opponent. This was followed—the fleet having failed to form line parallel to the enemy, and being still in two disordered columns—by signals for the lee or van division to engage the enemy's rear, and as some thought the weather division his centre; and ten minutes later came the new signal for passing through the line. The result was an action almost exactly like that of Nelson at Trafalgar—that is, though the leading ships duly acted on the combination of the two signals for engaging their opposites and for breaking the line, each at its opposite interval, the rest was a mêlée; for, since what was fundamentally a parallel attack was attempted as a perpendicular one, it could be nothing but a scramble for the rear ships.

In none of these actions therefore is there any evidence that Howe's attempt to impress the service with a serious scientific view of tactics had been successful, and the impression which they made upon our enemies suggests that the real spirit that inspired British officers at this time was something very different from that which Howe had tried to instil. Writing of the battle of St. Vincent, Don Domingo Perez de Grandallana, whose masterly studies of the French and English naval systems and tactics raised him to the highest offices of state, has the following passage: 'An Englishman enters a naval action with the firm conviction that his duty is to hurt his enemies and help his friends and allies without looking out for directions in the midst of the fight; and while he thus clears his mind of all subsidiary distractions, he rests in confidence on the certainty that his comrades, actuated by the same principles as himself, will be bound by the sacred and priceless law of mutual support. Accordingly, both he and all his fellows fix their minds on acting with zeal and judgment upon the spur of the moment, and with the certainty that they will not be deserted. Experience shows, on the contrary, that a Frenchman or a Spaniard, working under a system which leans to formality and strict order being maintained in battle, has no feeling for mutual support, and goes into action with hesitation, preoccupied with the anxiety of seeing or hearing the commander-in-chief's signals for such and such manoeuvres…. Thus they can never make up their minds to seize any favourable opportunity that may present itself. They are fettered by the strict rule to keep station, which is enforced upon them in both navies, and the usual result is that in one place ten of their ships may be firing on four, while in another four of their comrades may be receiving the fire of ten of the enemy. Worst, of all, they are denied the confidence inspired by mutual support, which is as surely maintained by the English as it is neglected by us, who will not learn from them.'[12]

This was probably the broad truth of the matter; it is summed up in the golden signal which was the panacea of British admirals when in doubt: 'Ships to take station for mutual support and engage as they come up;' and it fully explains why, with all the scientific appreciation of tactics that existed in the leading admirals of this time, their battles were usually so confused and haphazard. The truth is that in the British service formal tactics had come to be regarded as a means of getting at your enemy, and not as a substitute for initiative in fighting him.
