From: The History of Rome, by Theodor Mommsen
Translated with the sanction of the author by William Purdie Dickson
Hannibal had lost not quite 6000 men, and two-thirds of that loss fell upon the Celts, who sustained the first shock of the legions. On the other hand, of the 76,000 Romans who had taken their places in the line of battle 70,000 covered the field, amongst whom were the consul Lucius Paullus, the proconsul Gnaeus Servilius, two-thirds of the staff- officers, and eighty men of senatorial rank.
The consul Gaius Varro was saved solely by his quick resolution and his good steed, reached Venusia, and was not ashamed to survive. The garrison also of the Roman camp, 10,000 strong, were for the most part made prisoners of war; only a few thousand men, partly of these troops, partly of the line, escaped to Canusium.
Nay, as if in this year an end was to be made with Rome altogether, before its close the legion sent to Gaul fell into an ambush, and was, with its general Lucius Postumius who was nominated as consul for the next year, totally destroyed by the Gauls.
