Battle of Marengo - Austrian Attack

Austrian Attack

The Austrian troops advanced from Alessandria eastwards across the Bormida river by two bridges debouching in a narrow bend of the river (the river being not easily crossed elsewhere). Poor Austrian staff work prevented any rapid development of their attack and the entire army had to file through a narrow bridgehead. The movement began about 6 am with the first shots fired around 8 am, but the attack was not fully developed until 9 am.

The 1,200-man Austrian advance guard, under Colonel (Oberst) Johann Maria Philipp Frimont and a division of 3,300 men under FML O'Reilly, pushed the French outposts back and deployed to become the Austrian right wing, driving the enemy from Pedrabona farm, then heading south to tackle the French at La Stortiglione farm. The Austrian centre (about 18,000 under Melas) advanced towards Marengo until halted by GdD Gardanne's French infantry deployed in front of the Fontanone stream. On the Austrian left, 7,500 men under FML Peter Ott waited for the road to clear before heading for the village of Castel Ceriolo well to the north of the French positions. This move threatened either an envelopment of the French right, or a further advance to cut the French line of communication with Milan.

Gardanne's men gave a good account of themselves, holding up the Austrian deployment for a considerable time. When Gardanne's division was exhausted, Victor pulled it back behind the Fontanone and committed his second division under GdD Chambarlhac (this officer soon lost his nerve and fled). The French held Marengo village and the line of the Fontanone until about noon, with both flanks in the air. First, at 8 am, Melas hurled FML Karl Joseph Hadik von Futak's division (four battalions) at Victor's defences, supported by Frimont’s advance guard battery along the stream. Forced into a funnel by the bad ground and Fontanone stream, Hadik’s attack came under fire from two sides and failed, with Hadik being killed. The Austrian commander then committed FML Konrad Valentin von Kaim's division but this attack was also thwarted by 11 am. Finally, as the French position was reinforced by François Étienne de Kellermann's cavalry and Jean Lannes's formation was on the way, FML Ferdinand Johann von Morzin's elite grenadier division was sent in to attack Marengo village. Melas also committed a serious tactical blunder, detaching Generalmajor (GM) Nimptsch's brigade of 2,300 hussars and two artillery batteries back over the Bormida bridge to block the corps of General Louis Gabriel Suchet, which was mistakenly reported around 9 am from Acqui Terme to be approaching Alessandria from the south. Besides delaying the crossing of the Austrian left wing, this also meant that, being 30 kilometers away, Nimptsch's brigade would play no part in the battle.
