it seems like for Weygand the honors of the French Army was the most important drive. That's why he opposed bluntly the idea of capitulation , because it would have held the army responsible, and pledged instead for armistice, that involved the politicians. This distinction seems to have played a big role in the Weygand's and perhaps also Petain's position and have caused a lot of friction in the discussion between politicians and and military. Technically, after the experience with two (or more) saccessful evacuations across the channel, Weygands positions seems indeed questinable, esp. with the mediterranean ships still not at all engaged in the battle. Of course many ships that were still engaged around the channel and in the Atlantic would have been deployed around Spain to Southern France, but at the same times the whole of Southern France would still have to be conquered by the Germans.
