Royal Navy battles that slip from popular memory

Which Royal Navy battles are especially underrated or overlooked?

The second Battle of Copenhagen, Narvik, and much of the Mediterranean campaign are prominent examples.

The list of overlooked Royal Navy actions is long. The second Battle of Copenhagen is often eclipsed by the first. Narvik is intensely familiar to some audiences but completely absent from others' knowledge. Much of the Royal Navy's Mediterranean campaign also receives too little attention, making public memory uneven even when the operations themselves were important.
