Far from retiring down the Adige with his whole army, Bonaparte ordered Vaubois to block the gorges north of Trent with 10,000 men, while the remaining 22,000 troops set off in full pursuit of Würmser down the same pass that the Austrians were using. This was an extremely risky course to pursue, for during the operation the Army of Italy would be wholly dependent on what supplies it could seize locally, and even a temporary check on the Brenta might lead to starvation in the midst of the Alps."
