I want to know the answer to the following question:
Russia failed to help Austria during what war that took place in 1866?
All the background I'm provided with is that "Although it was Russia that was punished by the Paris Treaty, in the long run it was Austria that lost the most from the Crimean War despite having barely taken part in it.:433 Having abandoned its alliance with Russia, Austria was diplomatically isolated following the war,:433 which contributed to its disastrous defeats in the 1859 Franco-Austrian War that resulted in the cession of Lombardy to the Kingdom of Sardinia, and later in the loss of the Habsburg rule of Tuscany and Modena, which meant the end of Austrian influence in Italy.". Is that enough to answer the question?
Answer: no
