When Sahuc participated in the Battle of Raab on 14 June, only the 8th and 25th Chasseurs were present. While Emmanuel Grouchy and Louis-Pierre Montbrun's cavalry on the right flank defeated the Austrians opposed to them, his division guarded the left. As the Austrian army withdrew at the end of the battle, Sahuc's cavalry launched a pursuit which soon came upon some Hungarian "insurrection" (militia) infantry formed in squares. Though the raw Hungarians fired a scattered volley, they managed to fend off the first charge because the French horsemen attacked in a disorderly fashion. The second charge was better organized. One Chasseur regiment concentrated on one side of a square and broke through. Furious at their earlier repulse, they butchered the helpless Hungarians without mercy, even cutting down those who tried to surrender.
