Thanks. I've always thought that the PTs were cool, back to my days watching PT-109 on WTBS with my Dad, but never have I read that they were effective or important in a major engagement. It's always been something I've been curious about when reading about the Pacific in WWII to find them doing something big. I understand their important roles in the Solomons, for instance, and rescuing MacArthur, but I was curious if there was a major engagement that the PTs had played an important (and effective) role in that I didn't know about.
I've always thought that the idea of a dozen PT boats charging at the enemy battle line, letting loose a salvo of torpedoes, scoring some hits, and just as importantly breaking up the line was a cool idea. But like so many doctrinal roles that existed pre-war, the emphasis on the carrier and the lack of major fleet actions meant that what the navies intended and thought was important didn't necessarily jive with what actually happened.
I completely understand a little exaggeration for effect when it comes to marketing.
