1866奧普戰爭 (法國與普魯士傾中立問題)

1865普魯士想法國在遲d既奧普戰爭中立, 話會比邊度比拿破崙三世?
我見到有d話萊茵河區 , 有d就話比利時同盧森堡....

例如:
Bismarck had mentioned before the war the possibility of ceding territory along the Rhine to France

in Biarritz in September 1865 with Napoleon III, when Bismarck had let it be understood (or Napoleon thought he understood) that France might annex parts of Belgium and Luxembourg in exchange for neutrality.
