There were six TBFs at Midway (again, the original Grumman-built birds) stationed at Midway with one of the Marine torpedo squadrons. Five of the six were lost.
The primary torpedo plane in the American forces was the TBD Devastator, which were more or less massacred by the Japanese.
The "Hero" of the battle was the SBD Dauntless dive bomber, which claimed all four Japanese carriers (well, subs finished them off, I think, but the Dauntlesses did the damage).
