There were two flank movements: a
detachment of 300 men was sent to the right, into the mountains above the Urner-Loch tunnel (today ); another detachment of 200 men was ordered to cross the rocky
bed of the Reuss toward the other side and threaten the flank and rear of the French position beyond the river. Both these manoeuvres belonged to the number of those which are caused only by case of emergency, but both of them, owing to the troop energy, succeeded completely.
Major Trevogin with 200
jaegers descended to the stream with great effort and, overcoming even greater difficulties, began to cross the Reuss. The water was not deep,—knee-deep and only in some places waist-deep, but the main danger lay in the swiftness of flow. On reaching the shore, the men began to climb up steep, seemingly inaccessible slopes. In view of the success of this risky crossing, a whole battalion was sent in the footsteps of this team, which, not without losses crossed the river in a long
front, so that a considerable force was on the other side. It took not a little time to cross and then to move to the rear and flank of the French position, so that Colonel Trubnikov's
column, sent to bypass the Urner-Loch, fulfilled its task earlier. As soon as his men appeared on the slopes of the cliffs behind the tunnel, the French were in a state of confusion and hastily began to destroy the bridge. Lecourbe The cannon guarded the entrance to the Urner-Loch, where a fierce combat was fought on the same day. The French saved their cannon from Russian hands by throwing it into the river. The Russians rushed to the bridge; the main arch remained untouched, but instead of the second arch, there was a wide and deep gaping hole: the French had already managed, in spite of the Russian riflemen fire on the right bank, to block the way of the advancing enemy. There was a skirmish between both banks, which did not bring affair to an end, as it was impossible to repair the bridge under point-blank fire. By this time, however, the Russian troops who had forded to the French side had managed to ford a path through the mountainous heights of the left bank and began to descend towards the bridge. They were an impressive force, because
General Kamensky, who had received orders to cross the Betzberg ridge in the evening and follow Lecourbe to bypass the Urner-Loch and the Devil's Bridge, happened to be with them. The French could not hold on long in this place and began to retreat, while the left-bank Russian troops under Kamensky pursued them. Retreat became inevitable for the French also because, according to the campaign's general plan, the
Austrian general
Auffenberg, having descended from
Disentis by the
Maderanertal, occupied
Amsteg (now Silenen) on the Reuss and knocked out from there an insignificant French detachment; thus he found himself at the French rear. Although Lecourbe forced Auffenberg to withdraw along the Maderanertal, the Austrians still remained close by, maintaining a threatening position. As soon as it became clear that the French intended to retreat from the bridge, the Russians of the right bank rushed forward and began to make a hasty crossing over the ruined arch. They dismantled a nearby shed, dragged logs and planks, threw them over the dip and began to reinforce them with whatever they could find; Major
Prince Meshchersky 1st used his officer's scarf for this purpose, and after him other officers did the same. When the shaky and narrow bridges thrown over the rockslide formed some semblance of a crossing, the brave men began to cross, helping each other; some were cut off and crushed, others were killed or wounded, for the retreating French were still firing at the bridge. Soon the French shots fell silent or did not reach the bridge, and the temporary crossing became more passable, but it hardly helped the Russians to strengthen their pursuit, because it required a great deal of time for a small number of men; the assembled detachment of Kamensky was more terrible and dangerous to the French. Immediately the pioneers set about carefully repairing the damaged portion of the bridge, and at 5 o'clock the whole delayed column of Russian troops moved forward. ==Resume==
