With the partial withdrawal of the First Army, Prince Frederick Charles ordered a mass artillery barrage against Canrobert's position at St. Privat to prevent the Guards attack from failing too. At 19:00 the 3rd Division of Eduard von Fransecky's II Corps of the Second Army advanced across Ravine while the Saxon XII Corps cleared out the nearby town of Roncourt, along with the survivors of the 1st Guards Infantry Division, launched a fresh attack against the ruins of St. Privat. At 20:00, the arrival of the Prussian 4th Infantry Division of the II Corps and with the Prussian right flank on Mance Ravine, the line stabilized. Then, the Prussians of the 1st Guards Infantry Division and the XII and II Corps captured St. Privat, forcing the decimated French forces to withdraw. Some French officers incorrectly thought the Prussians were exhausted, so they urged a counter-attack. General Bourbaki, however, refused to commit the reserves of the French Old Guard to the battle because, by that time, he rightfully considered the overall situation a 'defeat' having run out of ammunition, being outflanked by Prussian artillery, and losing 1/4 of his men. By 22:00, firing largely died down across the battlefield for the night.
