resentment
"In France, the perceived preference of the British Navy for evacuating British forces at the expense of the French led to some bitter resentment" are you sure about that? the article states the BBC said they have waited until the very last man, so it means everyone was rescued.  
the French article states the French resentment vis-à-vis the BEF came from Gort's refusal to launch a "traditional counter-attack" as planned by French commander General Weygand. Gort wanted an evac as he claimed it was inevitable in the medium-term. the british chief of staff supported Gort and the british operation was launched instead of the french plan.
