The king, in pursuance of the plan he had marked out for himself, restrained his skirmishing more than was his wont. Nevertheless he lay close to Yvetot. His cavalry, swelling and falling as usual like an Alpine torrent, had now filled up its old channels again, for once more the mountain chivalry had poured themselves around their king. With ten thousand horsemen he was now pressing the Leaguers, from time to time, very hard, and on one occasion the skirmishing became so close and so lively that a general engagement seemed imminent. Young Ranuccio had a horse shot under him, and his father—suffering as he was—had himself dragged out of bed and brought on a litter into the field, where he was set on horseback, trampling on wounds and disease, and, as it were, on death itself, that he might by his own unsurpassed keenness of eye and quickness of resource protect the army which had been entrusted to his care. The action continued all day; young Bentivoglio, nephew of the famous cardinal, historian and diplomatist, receiving a bad wound in the leg, as he fought gallantly at the side of Ranuccio. Carlo Coloma also distinguished himself in the engagement. Night separated the combatants before either side had gained a manifest advantage, and on the morrow it seemed for the interest of neither to resume the struggle.

The field where this campaign was to be fought was a narrow peninsula enclosed between the sea and the rivers Seine and Dieppe. In this peninsula, called the Land of Caux, it was Henry's intention to shut up his enemy. Farnese had finished the work that he had been sent to do, and was anxious, as Henry was aware, to return to the Netherlands. Rouen was relieved, Caudebec had fallen. There was not food or forage enough in the little peninsula to feed both the city and the whole army of the League. Shut up in this narrow area, Alexander must starve or surrender. His only egress was into Picardy and so home to Artois, through the base of the isosceles triangle between the two rivers and on the borders of Picardy. On this base Henry had posted his whole army. Should Farnese assail him, thus provided with a strong position and superiority of force, defeat was certain. Should he remain where he was, he must inevitably starve. He had no communications with the outside. The Hollanders lay with their ships below Caudebec, blockading the river's mouth and the coast. His only chance of extrication lay across the Seine. But Alexander was neither a bird nor a fish, and it was necessary, so Henry thought, to be either the one or the other to cross that broad, deep, and rapid river, where there were no bridges, and where the constant ebb and flow of the tide made transportation almost impossible in face of a powerful army in rear and flank. Farnese's situation seemed, desperate; while the shrewd Bearnese sat smiling serenely, carefully watching at the mouth of the trap into which he had at last inveigled his mighty adversary. Secure of his triumph, he seemed to have changed his nature, and to have become as sedate and wary as, by habit, he was impetuous and hot.

And in truth Farnese found himself in very narrow quarters. There was no hay for his horses, no bread for his men. A penny loaf was sold for two shillings. A jug of water was worth a crown. As for meat or wine, they were hardly to be dreamed of. His men were becoming furious at their position. They had enlisted to fight, not to starve, and they murmured that it was better for an army to fall with weapons in its hands than to drop to pieces hourly with the enemy looking on and enjoying their agony.

It was obvious to Farnese that there were but two ways out of his dilemma. He might throw himself upon Henry—strongly entrenched as he was, and with much superior forces to his own, upon ground deliberately chosen for himself—defeat him utterly, and march over him back to the Netherlands. This would be an agreeable result; but the undertaking seemed difficult, to say the least. Or he might throw his army across the Seine and make his escape through the isle of France and Southern Picardy back to the so-called obedient provinces. But it seemed, hopeless without bridges or pontoons to attempt the passage of the Seine.

There was; however, no time left, for hesitation. Secretly he took his resolution and communicated it in strict confidence to Mayenne, to Ranuccio, and to one or two other chiefs. He came to Caudebec, and there, close to the margin of the river, he threw up a redoubt. On the opposite bank, he constructed another. On both he planted artillery, placing a force of eight hundred Netherlanders under Count Bossu in the one, and an equal number of the same nation, Walloons chiefly, under Barlotte in the other. He collected all the vessels, flatboats,—wherries,—and rafts that could be found or put together at Rouen, and then under cover of his forts he transported all the Flemish infantry, and the Spanish, French, and Italian cavalry, during the night of 22nd May to the 22 May, opposite bank of the Seine. Next morning he sent up all the artillery together with the Flemish cavalry to Rouen, where, making what use he could by temporary contrivances of the broken arches of the broken bridge, in order to shorten the distance from shore to shore, he managed to convey his whole army with all its trains across the river.

A force was left behind, up to the last moment, to engage in the customary skirmishes, and to display themselves as largely as possible for the purpose of imposing upon the enemy. The young Prince of Parma had command of this rearguard. The device was perfectly successful. The news of the movement was not brought to the ears of Henry until after it had been accomplished. When the king reached the shore of the Seine, he saw to his infinite chagrin and indignation that the last stragglers of the army, including the garrison of the fort on the right bank, were just ferrying themselves across under command of Ranuccio.

Furious with disappointment, he brought some pieces of artillery to bear upon the triumphant fugitives. Not a shot told, and the Leaguers had the satisfaction of making a bonfire in the king's face of the boats which had brought them over. Then, taking up their line of march rapidly inland, they placed themselves completely out of the reach of the Huguenot guns.

Henry had a bridge at Pont de l'Arche, and his first impulse was to pursue with his cavalry, but it was obvious that his infantry could never march by so circuitous a route fast enough to come up with the enemy, who had already so prodigious a stride in advance.

There was no need to disguise it to himself. Henry saw himself for the second time out-generalled by the consummate Farnese. The trap was broken, the game had given him the slip. The manner in which the duke had thus extricated himself from a profound dilemma; in which his fortunes seemed hopelessly sunk, has usually been considered one of the most extraordinary exploits of his life.

Precisely at this time, too, ill news reached Henry from Brittany and the neighbouring country. The Princes Conti and Dombes had been obliged, on the 13th May, 1592, to raise the siege of Craon, in consequence of the advance of the Duke of Mercoeur, with a force of seven thousand men.
