Private Seamus ‘Na Gaeilge’ O Fianghusa was asked to take part in the documentary by TG4 in 2010 as he began a tour of duty in Afghanistan.
The soldier is a member of the famed 69th ‘Fighting Irish’ regiment in New York.

The documentary ‘Dushlan’ (‘Challenge’) follows him from New York to Belfast and Donegal, then onwards to the extremes of the Afghan conflict.
