I want to know the answer to the following question:
How many 60-gun frigates did the Russians lose in the Black Sea?
All the background I'm provided with is that "During the siege, the Russians lost four 110- or 120-gun, three-decker ships of the line, twelve 84-gun two-deckers and four 60-gun frigates in the Black Sea, plus a large number of smaller vessels.". Is that enough to answer the question?
Answer: yes
