Such great schemes as his master's required, as he perpetually urged, liberality of expenditure and measures of breadth. He protested that he was not to blame for the ruin likely to come upon the whole enterprise. He had besought, remonstrated, reasoned with the king in vain. He had seen his beard first grow, he said, in the king's service, and he had grown gray in that service, but rather than be kept longer in such a position, without money, men, or means to accomplish the great purposes on which he was sent, he protested that he would "abandon his office and retire into the woods to feed on roots." Repeatedly did he implore his master for a large and powerful army; for money and again money. The royal plans should be enforced adequately or abandoned entirely. To spend money in small sums, as heretofore, was only throwing it into the sea.
It was deep in the winter however before he could fairly come to the rescue of the besieged city. Towards the end of January, 1592, he moved out of Hainault, and once more made his junction at Guise with the Duke of Mayenne. At a review of his forces on 16th January, 1592, Alexander found himself at the head of thirteen thousand five hundred and sixteen infantry and four thousand and sixty-one cavalry. The Duke of Mayenne's army, for payment of which that personage received from Philip 100,000 dollars a month, besides 10,000 dollars a month for his own pocket, ought to have numbered ten thousand foot and three thousand horse, according to contract, but was in reality much less.
The Duke of Montemarciano, nephew of Gregory XIV., had brought two thousand Swiss, furnished by the pontiff to the cause of the League, and the Duke of Lorraine had sent his kinsmen, the Counts Chaligny and Vaudemont, with a force of seven hundred lancers and cuirassiers.
The town of Fere was assigned in pledge to Farnese to hold as a convenient: mustering-place and station in proximity to his own borders, and, as usual, the chief command over the united armies was placed in his hands. These arrangements concluded, the allies moved slowly forward much in the same order as in the previous year. The young Duke of Guise, who had just made his escape from the prison of Tours, where he had been held in durance since the famous assassination of his father and uncle, and had now come to join his uncle Mayenne, led the vanguard. Ranuccio, son of the duke, rode also in the advance, while two experienced commanders, Vitry and De la Chatre, as well as the famous Marquis del Vasto, formerly general of cavalry in the Netherlands, who had been transferred to Italy but was now serving in the League's army as a volunteer, were associated with the young princes. Parma, Mayenne, and Montemarciano rode in the battalia, the rear being under command of the Duke of Aumale and the Count Chaligny. Wings of cavalry protected the long trains of wagons which were arranged on each flank of the invading army. The march was very slow, a Farnese's uniform practice to guard himself scrupulously against any possibility of surprise and to entrench himself thoroughly at nightfall.
By the middle of February they reached the vicinity of Aumale in Picardy. Meantime Henry, on the news of the advance of the relieving army, had again the same problem to solve that had been presented to him before Paris in the summer of 1590. Should he continue in the trenches, pressing more and more closely the city already reduced to great straits? Should he take the open field against the invaders and once more attempt to crush the League and its most redoubtable commander in a general engagement? Biron strenuously advised the continuance of the siege. Turenne, now, through his recent marriage with the heiress, called Duc de Bouillon, great head of the Huguenot party in France, counselled as warmly the open attack. Henry, hesitating more than was customary with him, at last decided on a middle course. The resolution did not seem a very wise one, but the king, who had been so signally out-generalled in the preceding campaign by the great Italian, was anxious to avoid his former errors, and might perhaps fall into as great ones by attempting two inconsistent lines of action. Leaving Biron in command of the infantry and a portion of the horse to continue the siege, he took the field himself with the greater part of the cavalry, intending to intercept and harass the enemy and to prevent his manifest purpose of throwing reinforcements and supplies into the invested city.
Proceeding to Neufchatel and Aumale, he soon found himself in the neighbourhood of the Leaguers, and it was not long before skirmishing began. At this time, on a memorable occasion, Henry, forgetting as usual, in his eagerness for the joys of the combat that he was not a young captain of cavalry with his spurs to win by dashing into every mad adventure that might present itself, but a king fighting for his crown, with the welfare of a whole people depending on his fortunes, thought proper to place himself at the head of a handful of troopers to reconnoitre in person the camp of the Leaguers. Starting with five hundred horse, and ordering Lavardin and Givry to follow with a larger body, while the Dukes of Nevers and Longueville were to move out, should it prove necessary, in force, the king rode forth as merrily as to a hunting party, drove in the scouts and pickets of the confederated armies, and, advancing still farther in his investigations, soon found himself attacked by a cavalry force of the enemy much superior to his own. A skirmish began, and it was necessary for the little troop to beat a hasty retreat, fighting as it ran. It was not long before Henry was recognised by the enemy, and the chase became all the more lively; George Basti, the famous Albanian trooper, commanding the force which pressed most closely upon the king. The news spread to the camp of the League that the Bearnese was the leader of the skirmishers. Mayenne believed it, and urged the instant advance of the flying squadron and of the whole vanguard. Farnese refused. It was impossible that the king should be there, he said, doing picket duty at the head of a company. It was a clumsy ambush to bring on a general engagement in the open field, and he was not to be drawn out of his trenches into a trap by such a shallow device. A French captain, who by command of Henry had purposely allowed himself to be taken, informed his captors that the skirmishers were in reality supported by a heavy force of infantry. This suggestion of the ready Bearnese confirmed the doubts of Alexander. Meantime the skirmishing steeplechase went on before his eyes. The king dashing down a hill received an arquebus shot in his side, but still rode for his life. Lavardin and Givry came to the rescue, but a panic seized their followers as the rumour flew that the king was mortally wounded—was already dead—so that they hardly brought a sufficient force to beat back the Leaguers. Givry's horse was soon killed under him, and his own thigh crushed; Lavardin was himself dangerously wounded. The king was more hard pressed than ever, men were falling on every side of him, when four hundred French dragoons—as a kind of musketeers who rode on hacks to the scene of action but did their work on foot, were called at that day—now dismounted and threw themselves between Henry and his pursuers. Nearly every man of them laid down his life, but they saved the king's. Their vigorous hand to hand fighting kept off the assailants until Nevers and Longueville received the king at the gates of Aumale with a force before which the Leaguers were fain to retreat as rapidly as they had come.
In this remarkable skirmish of Aumale the opposite qualities of Alexander and of Henry were signally illustrated. The king, by his constitutional temerity, by his almost puerile love of confronting danger for the danger's sake, was on the verge of sacrificing himself with all the hopes of his house and of the nobler portion of his people for an absolute nothing; while the duke, out of his superabundant caution, peremptorily refused to stretch out his hand and seize the person of his great enemy when directly within his, grasp. Dead or alive, the Bearnese was unquestionably on that day in the power of Farnese, and with him the whole issue of the campaign and of the war. Never were the narrow limits that separate valour on the one side and discretion on the other from unpardonable lunacy more nearly effaced than on that occasion.'
When would such an opportunity occur again?
The king's wound proved not very dangerous, although for many days troublesome, and it required, on account of his general state of health, a thorough cure. Meantime the royalists fell back from Aumale and Neufchatel, both of which places were at once occupied by the Leaguers: In pursuance of his original plan, the Duke of Parma advanced with his customary steadiness and deliberation towards Rouen. It was his intention to assault the king's army in its entrenchments in combination with a determined sortie to be made by the besieged garrison. His preparations for the attack were ready on the 26th February, when he suddenly received a communication from De Villars, who had thus far most ably and gallantly conducted the defence of the place, informing him that it was no longer necessary to make a general attack. On the day before he had made a sally from the four gates of the city, had fallen upon the besiegers in great force, had wounded Biron and killed six hundred of his soldiers, had spiked several pieces of artillery and captured others which he had successfully brought into the town, and had in short so damaged the enemy's works and disconcerted him in all his plans, that he was confident of holding the place longer than the king could afford to stay in front of him. All he wished was a moderate reinforcement of men and munitions. Farnese by no means sympathized with the confident tone of Villars nor approved of his proposition. He had come to relieve Rouen and to raise the siege, and he preferred to do his work thoroughly. Mayenne was however most heartily in favour of taking the advice of Villars. He urged that it was difficult for the Bearnese to keep an army long in the field, still more so in the trenches. Let them provide for the immediate wants of the city; then the usual process of decomposition would soon be witnessed in the ill-paid, ill-fed, desultory forces of the heretic pretender.
Alexander deferred to the wishes of Mayenne, although against his better judgment. Eight hundred infantry, were successfully sent into Rouen. The army of the League then countermarched into Picardy near the confines of Artois.
