Meagher was a leader of the Young Irelanders and later in 1848 was arrested for sedition after the Battle of Ballingarry. Sentenced to be hung, drawn and quartered Meagher and others were instead sent to Van Diemen's Land (Tasmania) but later escaped.
He eventually made it to the USA and founded the Irish Brigade in the Union Army before heading to Montana after the civil war ended in 1865.
