The option claims the siege would take "weeks" (presumably the estimation of our commanders, who should know their shit), and then "landing only once all activity has either ceased or been thoroughly suppressed". And Poptart is lawful, of course, so we can consequently expect our characters to behave like sensible people and not actually spend all our shells to saturation-bomb every square meter of Pelee island, but rather, as the text says, suppress them unti they can't mount an organized resistance, and then land and mop up, instead of landing asap as in the "assault" version.
Actually, the islands are small enough that trying to compel Victorian troops to surrender is probably viable, even by speakers mounted on ships. Victorians surrendering isn't unprecedented, at least, and they have to know they have literally no other way out. Is that a thing that's going to be attempted if we siege,
