Was the Raid on the Medway an epic British blunder?

Should the Raid on the Medway count as an epic naval blunder?

It was a major loss and a real blunder, but much of the result came from excellent Dutch intelligence work exploiting an ordinary British failure.

The British loss was enormous and involved a real blunder. British leaders failed to reason from missing information and underestimated what the Dutch could achieve. The Dutch also exploited intelligence and deception unusually well, turning British uncertainty into operational surprise. The consequences were exceptional, but the underlying mistake was a common human error rather than a uniquely spectacular one.
