The Army of Italy was fortunate in having capable generals. Catherine-Dominique de Pérignon led the left wing while Laurent Gouvion Saint-Cyr directed the right wing. Both became Marshals of France under Napoleon along with Joubert's chief of staff Louis Gabriel Suchet and division commander Emmanuel Grouchy. Joubert's generals wished to wait for Championnet's army to come up on their left around 20 August before advancing. However, Joubert believed that his orders to attack from the Directory were imperative and refused to delay. Saint-Cyr's wing moved north through the Bocchetta Pass and Gavi. At Serravalle Scrivia they besieged a castle held by four companies of Austrians. This position had been captured by Pyotr Bagration's 2,100-man Russian advance guard as recently as 9 August. Pérignon's wing had farther to march. This French column pushed some of Bellegarde's troops out of Terzo then swung east through Acqui Terme, Rivalta Bormida and Capriata d'Orba. Saint-Cyr arrived alone at Novi Ligure on 13 August, but Suvorov declined to attack, hoping to lure the French into the plains where his superior cavalry and artillery might prove decisive. That same day contact was established with Pérignon's approaching troops.
