six in the morning of the 7th of September
On the Russian side Bagration 's army formed the left , Beningsen 's the centre , and Barclay 's the right . The French force numbered about 150,000 , the Russian from 80,000 to 90,000 . The French had a thousand guns , the Russians 640 . At six in the morning of the 7th of September the French batteries opened fire along the whole line , and the Russians at once replied . The roar of artillery was incessant , and ere long the rattle of musketry swelled the din , as Davoust launched the division of Desaix , and Ney that of Campans , against three small redoubts in front of the Russian position . Impetuous as was the assault , the Russians received it with unflinching courage ; two of the Russian generals were wounded , but the assault was repulsed . Ney moved up another division , and after severe fighting the redoubts were carried .
