Zanzibar and the use of overwhelming naval force

What is an example of overwhelming naval firepower being used against limited opposition?

The short war at Zanzibar is offered as an example of Britain deploying overwhelming naval force and then imposing tougher terms after the fighting.

The brief war at Zanzibar is recalled as an example of naval force far exceeding the immediate opposition. Britain sent a squadron to compel compliance with its demands. The demands made before the fighting are distinguished from the more severe requirements imposed once force had been used. Overwhelming firepower was accompanied by an escalation in the terms demanded of the opponent.
