HMS Cossack's aggressive Narvik attack

What true naval episode sounds too implausible for fiction?

At Narvik, HMS Cossack forced her way over a blockship and fought from it to reach targets inside the port.

Cossack went over a blockship and fired while balanced on it rather than remaining outside the port. Standing off would have been safer but would not let the destroyer engage the targets she had been ordered to destroy. The violent improvisation matched the aggressive command culture associated with Tribal-class operations. An apparently reckless action followed a direct tactical purpose: get close enough to disable the ships and port facilities inside.
