Before Antietam
He was an Irish independence activist, served time as a (British) convict in Tasmania (Australia), and escaped to the US in 1852. Here he was a lawyer, lecturer, and political leader for Irish immigrants. In 1861 he organised a company in the 69th New York Militia and was appointed Major. He fought at First Bull Run. He then organised the Irish Brigade in New York, and in February 1862 was appointed Brigadier General of Volunteers commanding the 2nd ("Irish") Brigade/ 1st Division/Second (II) Corps at Yorktown, Seven Pines, Seven Days, and Second Bull Run.
On the Campaign
He continued in command of the the 2nd ("Irish") Brigade in the First Division of Richardson's Second (II) Corps. During the assault of his Brigade on the Sunken Road, he reported that his horse was shot out from under him and he was stunned in the fall. Army and newspaper rumors suggested that whiskey caused the fall. Whichever it was, he was relieved in Brigade command by Col J. Burke of the 63rd New York.
