Estimates
These figures were provided to J Caesar by the Remi in 57 BCE. The envoys of the Remi to Caesar were Iccus and Andecombogius.

German tribes
Condrusi, Eburones, Caerosi, and Paemani. They were living on the Gallic bank, (that is the left bank), of the Rhine.

Total strength
338,000 - probably an exaggeration by the Remi who were soliciting Caesar's help against these enemies.
