I would appreciate your assistance to analyze “subfossis”, in Julius Caesar, in Commentarii de Bello Gallico, Liber IV, Cap. XII:
Rūrsus his resistentibus, cōnsuētūdine suā ad pedēs desiluērunt, subfossīs equīs complūribusque nostrīs dēiectis reliquōs in fugam coniēcērunt…
In Spanish the translation of subfodere or suffodere is either to dig into the belly or to cut the legs at the knee level.
Thanks in advance.
Torto.
