“Technically, when the Moskva was sunk and the Makarov badly damaged, the Black Sea Fleet lost its only two command-capable ships and became the Black Sea Flotilla. With further losses including most of its air arm, several large landing ships and a submarine, the Black Sea Flotilla technically because the Black Sea Squadron.
If you are a Russian mother with a son in the Black Sea Squadron, pray for him, but don’t expect him home for Christmas.”
