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.
