I find in a biography of Giuseppe di Lampedusa (David Gilmour, The Last Leopard), the author of the The Leopard, something which shows you discover things in unexpected places.
Lampedusa visited England sometine in the 1920s.
"English eccentricity was also appealing, and he was amused by the dispute between Hilaire Belloc and Sir Charles Oman over military tactics in the Peninsular War. Staying in England at the time, he (lampedusa) read the newspaper reports of the two men tramping over Spain with supporters and period weaponry to prove their points. The whole thing was hilarious while it lasted and he regretted that the Spanish government had no sense of humour and asked them to stop."
I wonder what they were disputing. I cannot consult the newspapers without better dates, but I will try to find a biography of Hilaire Belloc in case that book has more detail.
