Ireland has a long tradition of not really having any wars of their own, so they go fight in other people's wars. Frequently on both sides at the same time.
In WWII, Ireland seemed to try very hard to forget that there was a war on. The period of time is known as The Emergency. When HMS Hood was blown up, the death of an Irishman aboard was reported in the Irish Times as being a 'boating accident'
Both the British and the Germans had plans to conquer and occupy Ireland, though the British one obviously was far more likely as the Germans had to deal with the UK first. Whilst officially neutral, Ireland did have a problem: The rules say that if you cannot enforce your neutrality, then it's fine for other combatant ships to patrol the waters in order to make sure the other side isn't using them. As a result, Ireland went on a frantic PT-boat purchase hunt, and eventually bought a few off the British. Most equipment ended up being British-made, though Ireland wasn't adverse to repairing and commandeering other countries' equipment that happened to land in the country. Lots of 'singletons' like a single Lockeed Hudson, or whatever.
I've already gone into the internment procedures in greater detail on another thread, but the 'lite' version is that for the first few years, Ireland detained all combatants that ended up in the country, and put them all together in one POW camp. To release tensions, everyone was let out on day passes, the system was respected by both sides. Ireland's leaning towards the allies became more and more blatant as time went on, however.
Another cartoon example of all the Irish people in the British forces was two British soldiers hunkered in a hole on the D-Day beaches, bullets whizzing over their heads. One's saying to the other "You can say what you like about DeValera, Seamus, but at least he kept us out of this war"
