 Caesar says the Nervii were almost annihilated in the battle, and is effusive in his tribute to their bravery, calling them "heroes".The Atuatuci, who were marching to their aid, turned back on hearing of the defeat and retreated to one stronghold, were put under siege, and soon surrendered and handed over their arms.However the surrender was a ploy, and the Atuatuci, armed with weapons they had hidden, tried to break out during the night.
