After the victorious Italian theater, Suvorov planned to march on Paris, but instead was ordered to Switzerland to join up with the Russian forces already there and drive the French out. The Russian army under General Korsakov was defeated by Masséna at Zürich before Suvorov could reach and unite with them. Surrounded by Masséna's 80,000 French troops, Suvorov with a force of 18,000 Russian regulars and 5,000 Cossacks, exhausted and short of provisions, led a strategic withdrawal from the Alps while fighting off the French. His host hoped to make its way over the Swiss passes to the Upper Rhine and arrive at Vorarlberg, where the army, much shattered and almost destitute of horses and artillery, went into winter quarters. When Suvorov battled his way through the snow-capped Alps his army was checked but never defeated. Suvorov refused to call it a retreat and commenced a trek through the deep snows of Panix Pass and into the 9,000-foot mountains of the Bündner Oberland, by then deep in snow. Thousands of Russians slipped from the cliffs or succumbed to cold and hunger, eventually escaping encirclement and reached Chur on the Rhine, with the bulk of his army intact at 16,000 men. For this marvel of strategic retreat, earning him the nickname of the Russian Hannibal, Suvorov became the fourth "Generalissimo" of Russia.
