But that aspect of war has faded, never to revive. Khaki kills the picturesque. Battle has grown grey, remote, invisible. It consists of trenches miles long, in which crouch unseen riflemen, shooting at moving specks of grey, distant thousands of yards; or in guns perched on hills five miles apart bellowing to each other across the intervening valleys. It is not merely that in a battle of to-day a soldier cannot see the features of the man he kills; he probably does not see him at all. The Highlanders at the Modder marched, panted, thirsted, killed, and were killed, for eight hours, and never saw a Boer! The soldier to-day sees neither the pin-pricks of flame nor the whiff of grey smoke which tell that somebody is shooting at him. For these are days of smokeless powder and long-range rifles. The man shot at only learns that circumstance as he catches the air-scurry of the passing bullet, and the atmosphere about him grows full of what one half-terrified war correspondent calls "little whimpering air-devils."

The interest of these books is that they bring back to us living pictures, as seen through living human eyes, of the great battles of a century ago—battles which have grown obsolete in fashion, but which changed the currents of the world's history, and of whose gain we are the heirs to-day.

It is curious, in a sense even amusing, to note how diversely their famous commander impressed these four soldiers, each occupied in recording for the benefit of posterity what he saw. Anton apparently never sees Wellington. The human horizon for the Scottish sergeant is filled with the colonel of his regiment. Harris gravely records how he saw the great Duke take his hat off on the field of Vimiero; for the rest, he held the ordinary view of the rank and file of the Peninsula that the Duke's long nose on a battle-field was worth 10,000 men. Kincaid says he was so anxious to see the Duke when he joined the army that, as he puts it, "I never should have forgiven the Frenchman that killed me before I effected it." He was soon gratified, but seems quite unable to give any description of the great soldier. He contemplated him with the sort of frightened awe with which the youngest boy at Eton would look at "the head" arrayed in his official robes; a vision to be contemplated from a safe distance, without the least desire for a nearer and personal acquaintance.

Mercer came closer to the great Duke, and regards him with a cooler and therefore a severer judgment. Mercer had boundless confidence in Wellington as a battle-leader, but not the least affection for him as a man, and it is plain he had no special reasons for affection. Wellington had many fine moral qualities, but anxious consideration for other people, or even calm justice in his dealings with them, is not to be included in their catalogue. The famous general order he issued after the retreat from Burgos is an example of the undiscriminating harshness with which Wellington could treat an entire army. And that element of harshness—of swift, impatient, relentless discipline that could not stay to discriminate, to weigh evidence, or even to hear it—was one great defect of Wellington as a general. About his soldiers he had as little human feeling as a good chess-player has about his pawns. Mercer never came into intercourse with the Duke but with disaster to himself, a disaster edged with injustice.

When his troop was in France, Mercer says he ran an equal risk of falling under the Duke's displeasure for systematically plundering the farmers, or for not plundering them! If a commander of a battery allowed his horses to look in worse condition than those of another battery he was relentlessly punished. "The quick eye of the Duke would see the difference. He asked no questions, attended to no justification, but condemned the unfortunate captain as unworthy of the command he held, and perhaps sent him from the army." But the official amount of forage supplied was quite insufficient for the purpose of keeping the horses in high condition. Other troops supplemented the supply by "borrowing" from the farmers, and there was no resource but to imitate them, or to risk professional ruin by presenting at parade horses inferior in look to those of other troops nourished on mere felony. Wellington forgave neither the unlicensed "borrowing" of the officers nor the want of condition in their horses. Yet one fault or the other was inevitable.

The Duke, it seems, "had no love for the artillery," and all his harshness was expended on that branch of the service. "The Duke of Wellington's ideas of discipline," says Mercer, "are rigid; his modes of administering them are summary, and he is frequently led into acts of the grossest injustice." Thus the owner of a building where some of Mercer's men were quartered—a thorough rogue—complained to the Duke that the lead piping of his house had been plundered and sold by the guilty British gunners. Wellington made no inquiry, took no evidence. A staff officer rode to Mercer's quarters one day with a copy of this complaint, on the margin of which was written in the Duke's own hand-writing: "Colonel Scovell will find out whose troop this is, and they shall pay double." This was the first intimation the unfortunate Mercer had received of the charge against him. The Frenchman pretended to estimate his loss at 7000 francs, and Mercer was advised, in high quarters, to pay this sum in order to escape the Duke's wrath. Mercer appealed to Sir George Wood, who told him his only chance lay in evading payment as long as he could; then the Duke might be caught in a more amiable mood. The actual thief—one of the French villagers—was discovered and convicted; but this circumstance, Mercer records, "has not in the least altered my position with the Duke of Wellington; for none dare tell him the story; and even Sir Edward Barnes, who kindly attempted it, met with a most ungracious rebuff!"

The French scoundrel, meanwhile, was dunning Mercer to get his 7000 francs. The situation remained thus for weeks, till the audacious Frenchman ventured on a second interview with the Duke. The Duke had dismounted, as it happened, in a very ill humour, at the door of his hotel, and the Frenchman pursued him up the grand staircase with his complaint. The Duke turned roughly upon him, "What the devil do you want, sir?" The Frenchman presented his bill with a flourish, whereupon the Duke exclaimed to his aide-de-camp, "Pooh! kick the rascal downstairs!" The Frenchman and his bill thus vanished from the scene; but Mercer's comment is "that I eventually escaped paying a heavy sum for depredations committed by others is due, not to the Duke's sense of justice, but only to the irritability of his temper."

On another occasion Sir Augustus Fraser, meeting him, said, "Mercer, you are released from arrest." Mercer stared: but on inquiry, discovered that he had been officially under arrest for a fortnight without knowing it. At a review, just before passing the saluting point, a horse in the rear division of his battery got its leg over the trace. The limber gunners leaped smartly off, put things straight, and jumped to their places again; but the division, with their 18-pounders, had to trot to regain place, and were just pulling up when they reached the saluting point. The precise and rhythmical order of the troop was a little disturbed, and Wellington, in a burst of wrath, put Sir Augustus Fraser himself, who was in command of all the artillery, the major in command of the brigade, and Mercer, the captain of the guilty troop, under arrest, where—happily all unconscious—they remained for a fortnight. Later Mercer wished to apply for leave of absence, but Sir George Wood declined to present the request, as he said, "'It would not be prudent just now to remind the Duke of me in any way.' Rather hard and unjust this," is Mercer's comment.

Mercer, however, tells one story, which shows that the Duke of Wellington was capable of sly satire at the expense of the French. An English officer walking on the boulevard was rudely pushed into the gutter by a French gentleman, whom the Englishman promptly knocked down. The Frenchman, it turned out, was a marshal. He complained to the Duke, but could not identify the officer who had knocked him down. The Duke thereupon issued a general order, desiring that "British officers would, in future, abstain from beating marshals of France."
