   • c. 52 BCE, Julius Caesar, Commentarii de Bello Gallico 6.3:

     Itaque nondum hieme confecta proximis quattuor coactis legionibus de improviso in fines Nerviorum contendit et, priusquam illi aut convenire aut profugere possent, magno pecoris atque hominum numero capto atque ea praeda militibus concessa vastatisque agris in deditionem venire atque obsides sibi dare coegit.

     Accordingly, while the winter was not yet ended, having concentrated the four nearest legions, he marched unexpectedly into the territories of the Nervii, and before they could either assemble or retreat, after capturing a large number of cattle and of men, and wasting their lands and giving up that booty to the soldiers, compelled them to enter into a surrender and give him hostages.
