They were not MASSIVELY outgunned at Trafalgar. It was a 1:1 battle, which the British won because they had the more experienced fleet.
Nor were they MASSIVELY outgunned in the Battle of Britain. In fighter power, which is what counted, they were outnumbered about 1.5 to 1, which isn’t nice odds, but it’s not massive either.
This isn’t trafalgar or the B.O.B. The scenarios are completely different.
