RTÉ, the Irish state broadcaster, currently has an intriguing documentary available on its online radio pages concerning Michael Keogh, Mexican War veteran and founder member of Casement's Irish Brigade, the brigade set up to fight the axis cause against the 'ould enemy. I highly recommend it (I remember when it was first transmitted in 2011 and enjoyed it tremendously).
Link to RTÉ Page "Documentary on One"Michael ended up fighting for both sides during World War One, winning medals for courage during both stints - so you could say he had evidence that his other rather colourful claims shouldn't be lightly dismissed. One of those claims was that, during his German stint, he actually saved the
life of his regiment colleague - young Corporal Adolf Hitler.
His memoirs, disgracefully stolen from him on his deathbed, turned up a few years ago for sale on the internet and were re-acquired by his family. The programme's original airing coincided with their publication.
'With Casement's Irish Brigade', is written by Michael Keogh and compiled by Kevin Keogh. It is available from Choice Publishing Ltd, Drogheda, Co. Louth.
