Three anonymous torpedo vessels engaged in a strike against the former HMS Manchester, which was being sold to Japan as part of technology transfer agreement. Agents acting on behalf of Russian interests were suspected, but nothing was ever proven. The nature of the operation implied an intimate understanding of the disposition and movement of Imperial forces, which threw suspicion elsewhere. A report was later prepared for the Admiralty, but this was never made public. Not fully trusting the British, Japan subsequently sought closer ties with Brazil and later Chile. Raw materials became a better source of leverage than shipbuilding capacity, as the reverse engineering of the Construction Cylinders made the latter largely moot.

Cpl. Masaru wasn't in his post at the moment. He's in the torpedo room, possible sneaking out for a cigarette or two. He accidentally hit the detonator with his knee. His last word is
Nicely done dude!
