During the Hundred Days, Subervie was given the 5th cavalry division (1,487 men and 6 guns) in the I Cavalry Corps of General Pajol with which he served in the Battle of Ligny. Detached from his parent corps, Subervie's division accompanied the Army of the North and Napoléon to Waterloo. At Waterloo, after the emperor noted that the Prussians were marching to aid the Duke of Wellington, he was sent together with Lobau's VI Infantry Corps to hold the French right flank while the emperor faced Wellington. In this capacity he was involved in fighting the Prussians around Plancenoit.
