Are you saying that Sidney Smith was the only British naval officer capable of undertaking the cutting out operation in Toulon harbor? I haven't found that to be true of the Royal Navy officers in general during the period. Cutting out operations were one of the skills at which Royal Navy officers excelled, both against the French and the US Navy. The US Navy was also skilled in that type of operation, witness Stephen Decator and the USS Intrepid in Tripoli harbor burning the captured frigate USS Philadelphia which earned praise from Nelson as 'the most daring act of the age.'
Not saying that at all. To say that would be nonsense... which is probably why you thought of it. ;-)
Indeed, cutting out operations were generally the task assigned to young lieutenants looking for some "glory."
Toulon, however, was not a cutting out operation, it was an incendiary operation.
When it comes to special/guerrilla war type operations, the first Georgian naval officer that comes to mind is Sir Sidney Smith.
MY point (not your point) was that for British naval interests, they were very lucky to have on hand the best man for the job, undoubtedly the very best incendiary in the Royal Navy, Sir Sidney Smith.
