The Warsaw Uprising in 1943 was begun with 11 guns the Jews managed to find/steal. They used those to get others. It took the Germans a month to wipe them out. With 11,000 guns or more, they could have held out longer. Winning was out of the question in that instance. However, not every struggle between unequal opponents comes out that way....Vietnam, Afghanistan, and other insurgencies are proof that superior technology does not automatically confer victory.
And from that start, they held out longer than France.
