But the culpable negligence of the Africans intoxicated with victory
wrested from them its consequences; they allowed themselves to be
surprised in a deep sleep during the morning twilight by the Roman
troops which had been in some measure reorganized during the night,
and were fortunately dispersed.
Thereupon the Roman army continued
its retreat in better order and with greater caution; but it was
yet again assailed simultaneously on ail the four sides and was in
great danger, till the cavalry officer Lucius Cornelius Sulla first
dispersed the squadrons opposed to him and then, rapidly returning
from their pursuit, threw himself also on Jugurtha and Bocchus at
the point where they in person pressed hard on the rear of the
Roman infantry. Thus this attack also was successfully repelled;
Marius brought his army back to Cirta, and took up his winter
quarters there (648-9).
