After 14 hours of continuous battle, the only result was enormous loss of life. Authors differ greatly in their assessments of the relative losses: estimates of Russian casualties range from about 15,000 to 20,000 killed or wounded and 3,000 men, 23 cannon and 16 colors captured. Count von Bennigsen estimated his losses at up to 9,000 dead and 7,000 wounded. The French lost somewhere between 10,000 and 15,000 and 25,000–30,000 with five eagles lost. David G. Chandler suggested as many as 25,000 French casualties, although conceding it is impossible to be certain. According to estimates of German historian Horst Schulz, the French lost 4,893 men killed, 23,598 wounded and 1,152 missing in action, which makes a total of 29,643.
