Hi Matt, you're right, theres very little written and quite difficult to find. So far, all I've come up with, is an e-book: The Irish and English in Italy's Risorgimento. by Mary Jane Cryan. An Irish woman who lives in Italy. Basically the Legion was raised in August 1860 , sailed to Naples in September. Their baptisum of fire was the Battle of Porto Capua. It all ended in tears by Xmas, due to a certain Mr styles embezzling funds destined for Garibaldi and the cause. They were called Excursionists, because the Foreign Service Act forbid the enlistment for foreign Kings, governments etc. They got around this Act by claiming they were on an excursion to Mount Etna and as the area was quite unsettled, they were provided with weapons for self defence! The Irish Legion were raised for the Pope, at about the same time and had a worse time of it. As the Pope and the Austrians were against Italian unification and they lost.
