9:00 am the bulk of his division had reached a location just to the north. However, Grenier's advance elements soon appeared to the southwest. Jellacic sent his 60 horsemen and General-Major Ignaz Legisfeld's light brigade to hold off the French on a ridge just west of the town. At 10:00 am, Seras attacked Legisfeld's line but his troops were driven back. Seras kept up the pressure and soon the Austrian division commander brought Ettingshausen's brigade of approximately 5,000 soldiers into action. Jellacic anchored his left flank on the Mur and planted his right flank in the hills to the north. Durutte's division arrived in the afternoon, giving Grenier a superiority of about 15,000 to 8,000. Another authority gives the French numerical advantage as 12,000 to 9,000 troops. Grenier prepared a two-division assault. He placed General of Brigade Louis Gareau's brigade of Seras in the first line. General of Brigade François Valentin of Durutte's division stood in the second line. Seras' second brigade under General of Brigade Roussel was sent through the hills to envelop Jellacic's right flank and cut the road leading back to Mautern. Durutte's remaining brigade, led by General of Brigade Joseph Marie, Count Dessaix, was held in reserve by Grenier. The French commander also sent two battalions of the 62nd Line Infantry Regiment along the south bank of the Mur to turn the Austrian left flank. With only one landwehr and one Grenzer battalion to face Roussel's envelopment, Jellacic withdrew one battalion of the Esterhazy Infantry Regiment # 32 from the center to shore up his right flank. Other troops had to be sent to face the threat from the 62nd Line. At 4:00 pm, Grenier's assault smashed the weakened Austrian center. Roussel also broke through on the flank to cut the road to the north. The Austrian fled in rout to the northeast along the Mur valley, closely pursued by the French. Grenier harried his beaten foes through Leoben, 7 km northeast, and Bruck an der Mur, 20 km northeast. At Bruck, Jellacic's survivors turned south, following the Mur valley to Graz. Only 2,000 of Jellacic's troops reached Graz the next day. Result Grenier wrecked the Northern Division. Instead of providing a substantial reinforcement to Archduke John, Jellacic brought in less than one-third of his command. The Austrians suffered 423 dead, 1,137 wounded, 4,963 captured, and 50 missing. French losses numbered 200 killed, 400 wounded, and
