The Sinking of the R.M.S. Leinster in World War I

The Story of the sinking of the R.M.S. Leinster - The Kingstown (re-named Dun Laoghaire) to Holyhead Mailboat.

R.M.S. Leinster - 1897 -1918

On the 10th of October 1918 at a little before nine o'clock in the morning, the City of Dublin Steam Packet Company owned mailboat - the R.M.S. Leinster - left Kingstown (now Dun Laoghaire) on route for Holyhead. Three members of the Royal Navy manned 12 pound guns on board as a precaution. Including these three men there totalled 771 on board. Of these, 489 were military and 180 were civilian passengers. 22 Dublin Post Office workers and 77 crew accounted for the rest.

An hour into her journey, a torpedo was launched by U-boat UB-123, which just missed the Leinster. A second torpedo struck the Leinster in the area of the sorting room, and just one of the 22 workers inside would survive. Captain William Birch - Irish, but living in Holyhead in a property named 'The Sycamores' - gave the order to turn the ship and attempt to get back to Kingstown harbour. The third torpedo struck amid ships in the engine room, causing devastating damage, and the ship began to sink. Survivors found themselves struggling in rough seas, and by the time rescue boats arrived 501 would have perished.

This was the largest maritime disaster ever witnessed on the Irish Sea, with multi national loss of life, including Welsh, Irish, Scottish, English, Canadians, Americans, New Zealanders and Australians.

In the 1990`s, one of Leinster's anchors was raised from the depths, and now rests opposite the Carlisle Pier in Dun Laoghaire (was Kingstown), from where she sailed on that fateful and tragic day. The Leinster now lies about 12 miles off shore, with her severed bow pointing south. The main part of the wreck, which though still intact is extensively damaged, is slowly sinking below the sands.

Following the war the City of Dublin Steam Packet Company could not financially recover from the loss of the Leinster and its' other ships, and in 1920 the Irish Mail contract was finally awarded to the companies rival for 70 years - the London and North Western Railway Company.
