Vercingetorix therefore crossed the powerful river Elave (now Allier, a tributary to the Loire) at Nevers, and started marching up and down the bank, mirroring Caesar's movements and destroying all the bridges to keep him from crossing, the purpose presumably being to destroy part of his force as he attempted to cross. Realizing Vercingetorix's plan, Caesar resolved to trick him and cross under his very nose.
