The next great exodus of Irishmen to serve in the armies occurred after the Siege of Kinsale. An Irish regiment was formed in 1605 and Colonel Henry O'Neill was placed at its head. Five other Irish regiments were formed between 1632 and 1646 and were placed under the command of The Earl of Tyrconnell, Owen Roe O'Neill, Thomas Preston, Patrick FitzGerald and John Murphy. Later they were joined by Irishmen who had served in the army of Henri de Bourbon and Charles IV. The difficulties that plagued them at home were carried to the continent when O'Donnells refused to serve under O'Neills and tension existed between the Old English and the Old Irish. This was especially evident in tensions between O'Neill and Preston.
