From The Crimean War: A History, by Orlando Figes (Metropolitan, 2011), Kindle Loc. 403-410:
The Russian annexation of the Crimea, in 1783, was a bitter humiliation for the Turks. It was the first Muslim territory to be lost to Christians by the Ottoman Empire. The Grand Vizier of the Porte reluctantly accepted it. But other politicians at the Sultan’s court saw the loss of the Crimea as a mortal danger to the Ottoman Empire, arguing that the Russians would use it as a military base against Constantinople and Ottoman control of the Balkans, and they pressed for war against Russia. But it was unrealistic for the Turks to fight the Russians on their own, and Turkish hopes of Western intervention were not great: Austria had aligned itself with Russia in anticipation of a future Russian-Austrian partition of the Ottoman Empire; France was too exhausted by its involvement in the American War of Independence to send a fleet to the Black Sea; while the British, deeply wounded by their losses in America, were essentially indifferent (if ‘France means to be quiet about the Turks’, noted Lord Grantham, the Foreign Secretary, ‘why should we meddle? Not time to begin a fresh broil’).
