Holy shiiize, that's the most convenient rebellion I've ever seen! The plot is discovered and most conspirators are captured? Don't worry, one of them manages to convince everyone it was all a joke! Need a lot of boats? Why, the local bandit chief has a whole fleet in his backyard! Captured and about to die in a prison? Big Mom to the rescue! Chaos ensues, the prison is taken over, they get thousands of supporters, and also the support of the yakuzas as a unexpected bonus! And now that they need weapons, I bet that sword thief has an army's worth of sword in his basement! Truly, I love it when a plan comes together.
