Another song you might like is a 19th-century song - After Aughrim. This commemorates the Battle of Aughrim in 1691, when the Irish were finally (for the moment) defeated. The Voice Squad have a nice version of it on Liam O'Flynn's album Out to an Other Side.

And about the same era - but this time actually an 18th-century song - is Eamonn a' Chnoic, where a woman is singing to her husband/lover/brother/whatever as he beats on the door outside, saying that though she will conceal him behind her skirts, they will both be quenched by the cannon's peal. The first lines, translated, mean: "Who is that outside, fever in his voice, beating on the closed door? It is Eamon of the Hill, who is drowned, cold and wet, from walking hidden in the hills and the glens".
