The powers held exaggerated ideas of the Sonderbund forces. It could hardly put on foot more than thirty thousand regular troops. The _Landsturm_, it is true, meant a more considerable number of men, but not having received sufficient organisation could not be compared to the excellent reserves of the large cantons, and did not give the help expected of them. Far from one another, the separatist states could only with difficulty lend one another aid. The original cantons tried nevertheless to keep their ways open by means of boldness in offensive actions. Even before the diet began its campaign, the men of Uri seized the St. Gotthard passes (November 3rd); threw themselves across the Levantina, surprised three thousand Ticinese encamped at Airolo, and drove them as far as the Moesa bridge. But arrived at this point, they found themselves face to face with Grisons and Ticino militia, superior to them in number, who stopped their progress. The expedition had no other result than that of holding back two thousand excellent soldiers from the places where decisive blows were to be struck. Another attempt, made from Lucerne, to penetrate into Catholic Aargau and to free Fribourg, by means of a diversion, had no better success. _The Capitulations of Fribourg and Lucerne End the Sonderbund_ Without taking much account of these movements, Dufour occupied himself only in concentrating his forces so as to surround the Sonderbund states, on all their accessible frontiers. His provisions were assured, his hospital organised. Immediately upon the rupture being announced, Colonel Ochsenbein, who presided over the diet, left office to put himself entirely at the disposition of the general-in-chief. The general placed him at the head of the Bernese reserves, which composed his seventh division and which he assimilated with the active troops. He stationed them first on the Lucerne frontier, and when he arranged to draw near Fribourg, he called Ochsenbein to advance towards that capital, in order to make the enemy think he would attack from the eastern side. However, twenty thousand men and fifty-four artillery pieces, under colonels Rilliet, Burkhard, and Donatz, advanced from the north and west by different routes, and kept their movements secret that they might arrive on the same day at the gate of Fribourg. On the 13th the town was surrounded. An experienced leader, Colonel Maillardoz, had raised defences all round, and they had prepared to attack these exterior forts when the Fribourg government, recognising the impossibility of resistance, gave up the town, dismissed the troops, and renounced the Sonderbund. The taking of Fribourg would not have cost the federal army a single man if through a mistake a Vaudois troop had not rushed under fire from the Bertigny redoubt, which resulted in seven killed and a large number wounded.
