Thank you so much Petrov 20 4, 8:54pm

@CorruptUser I was thinking that myself. From memory, the use of dummy depth charges (and they were throwing lighter stuff before the dummy depth charges) was something that the Americans had warned the Russians they were going to do to warn any submarines that got too close that a) they'd been seen and b) if they didn't surface or otherwise back off, they might get fired upon for real. Arkhipov's submarine, however, had been underwater long enough that it hadn't received the message. Eventually the submarine surfaced, hoping it wouldn't be sunk as soon as it did so, which turned out to be the right thing to do.
