Well, to make your point you had to expand the subject from: guerrilla war instigated, directed, and supplied by a military organization, to more generalized popular revolts.

Popular revolt, usually for independence, supported by foreign power, has nothing specific to Sir Smith.

Catalunia revolted against Spain during War of Spanish succession, with British and Austrian support.

I don't know enough about the War of Spanish Succession to comment.

Indian warfare in North America was supported by British and French, triggering early start of Seven Year War there.

To my knowledge, this was largely confined to the French aligning with the Indians. Have no knowledge of the British military organizing, supplying, and leading Indians in a guerrilla war against Americans.

Vendée and Chouannerie were popular uprising, with british support in weapons, royalist agents, Navy, and even full scale landing attempt at Quiberon.

The Vendée, again I'm no expert, was closer to a straight up war rather than a guerrilla war. They had British support but they were not led by British officers.

So was Royalist revolt of Toulon, with british help

There is no aspect of guerrilla war at Toulon. Although, British army officers did lead some Spainish, Neapolitan, Sardinian, troops there but these were all regular military. Not aware of any non military residents of Toulon being organized and led by British officers.

Irish revolt of 1798 expected support from French revolutionary state.

Certainly nothing close to British military support for the Irish. As I recall there was some British organizing local militia but that's not guerrilla warfare.

Balkans revolted repeatedly against Ottoman with Russian support

Again, you are tossing a wide net to include general revolts.

So any major power would help popular revolt, provided they see a gain

Not true at all. Austria in particular had a strong bias against anything close to a popular uprising. The closest they ever got was in 1809 with Tyrol and that didn't work out so well and they never attempted the same thing again. Napoleon also had strong reservations against anything resembling a popular revolt.

Sir Sidney Smith's actions in Calabria in 1806 were exceptional, if not unique. There are few instances in this period where a foreign military power goes into another country, calls for insurrection, supplies weapons to the population, organizes those forces, directly supports those local forces with regular troops/sailors, and leads the combined forces with their own officers, in a guerrilla war. Which is exactly what Sir Sidney did in Calabria. The next closest example in this time period would again be Sir Sidney when he did basically the same thing at the Siege of Acre.

Of course, Spain 1808 changed everything.
