Without entering the town, Bourbon therefore turned aside from Chambéry, and took the way towards Aix. They walked for a couple of hours, when worn out almost by fatigue, they approached a châlet, and obtained accommodation for the night. The account they gave of themselves satisfied the master of the châlet, and they left early next morning without exciting his suspicion. On reaching the Lac de Bourget, they hired a boat, and were rowed to the farther end of that beautiful lake. Having reached Seyssel in safety, they crossed the Rhone, and sought shelter in a châlet for the night. Next morning they again began to ascend the Jura, and alter crossing several peaks, and tracking more than one gloomy gorge, they came in sight of the ancient town of Nantua, seated on the borders of a lake. Not daring, however, to enter the town, they again sought the shelter of a châlet. A mountainous ridge now only separated them from the Franche-Comté. This ridge crossed, Bourbon's danger would be over. At break of day the fugitives again started on their journey. It was a lovely morning, and the beauty of the scenery might have tempted them to linger on their way; but they hurried on, eager to cross the frontier. On attaining the summit of a mountain commanding the beautiful valley, in which lay the old town of Nantua and its lake, Bourbon paused for a moment to survey the lovely prospect, and then became aware that a small troop of cavalry was ascending the heights. Pointing out the danger to his companions they all three started off, and, after crossing the summit of the mountain, dashed down the opposite side. Near the foot of the acclivity there was a thick dark wood, and into this they plunged, though not unperceived by their pursuers, who by this time had gained the brow of the mountain. At the sight, the soldiers dashed down the hill, a portion of the troop entering the wood, while the others rode round it. By this manouvre they hoped to secure their prey; but they were foiled. Three of the men-at-arms, who had penetrated into the thicket, were suddenly set upon by Bourbon and his companions, and compelled to give up their horses. Being thus provided with steeds, the fugitives suddenly burst out of the wood and galloped towards the frontier, which was marked by the river Ain, now only half a league off. On a mount on the farther side of the river stood a fort garrisoned by the soldiers of the Emperor, and it was towards this point that the fugitives now shaped their course. But they were hotly pursued by their enemies, while another small band of cavalry, sallying from a fort on the French side of the river, sought to cut off their retreat. Before the latter could come up, however, Bourbon and his companions had reached the river, and dashing into it without hesitation, their horses safely across.
