A bit of a stretch, but Syracuse?

An island just off the coast of Sicily (about 50m away, at least now). The Athenians landed troops on Sicily, but never got a beach head on the island of the city itself. The eventual defeat of the Athenian navy there led to their entire force being destroyed/captured.
Timoleon of Corinth managed it in 343BC.

Thanks for this because it reminded me of Alexander's Siege of Tyre, an offshore island that Alexander couldn't reach because he had no navy so he built a causeway from shore to the island. It almost worked, but he ended up building a navy anyway.

*Australia is difficult to conquer due to its size and thinly populated interior.


* Australia is the world's largest island or the world's smallest continent, take your pick.

Would you consider Haiti?

It's very small, but is the site of the only fully successful slave revolution in the history of the world. Notice I said "fully successful".

The slaves horrendously outnumbered the owners (this is usually the case) but were alternately able to carry out guerilla warfare and retreats to inaccessible places, and just wore the French out.

The OP said "invaded"? The French on the island were quickly overpowered, so France sent boatloads of military to settle things ... and they left defeated. "Invasion" of French troops failed.

OK, I'm stretching it a bit, but a relatively unorganized, ill equipped, untrained group of sugar cane cutters defeated the experienced, organized, well equipped, highly trained French.

I'm talking about island nations or states that were at war with a power on a nearby mainland. The mainland power had a large army but no navy or at least not a large enough navy to invade the island. Examples would include Britain in 1805 and 1940, Taiwan in 1949, Japan vs the Mongols. Any others?
As far as I know, Greenland was never occupied by the Germans during WWII.

Britain is probably the best example of an island holding out against a country (or countries) that hugely dominates the mainland, thanks to a small strip of water and strong navy and good coastal defences. Not only were the Germans repelled in WW2 as well as France in the Napoleonic wars, but also Spain and France throughout the last 1000 years or so.

Of course there are also times when we HAVE been invaded successfully such as by the Romans, Vikings and the Normans .
