Last October, we marked the centenary of Ireland’s worst maritime disaster, the First World War sinking of RMS Leinster, shortly after it sailed from Dún Laoghaire. A German submarine condemned 564 souls to watery graves.

This coming month of October sees the commemoration of the sinking of the RMS Leinster on the Irish sea just outside of Kingstown (Dún Laoghaire) on October 10, 1918. It was torpedoed by a German U-boat with the loss of more than 500 lives. To date, it remains the single biggest loss of life on the Irish Sea.
