I still think the French could have held them. The French soldiers could fight. Almost every book I've read gives them credit for being good soldiers. It was the ridiculous last-second run to the north that wore them out.

Given an objective like holding the line, I think there would have been no problem, and in such a situation the French would have been able to resupply more rapidly than the Germans. Throw in a handful of British divisions, maybe some Poles, and it's even easier. Whatever problems the German artillery caused would have been dealt with somehow. Maybe instead of the RAF frantically trying to take out bridges over the Meuse it would have been sent against the advancing German heavy guns.
