A Californian student at University College Cork will help remember the arrival of the US navy in Ireland — 100 years to the day after her great-grandfather commanded the flotilla that sailed into Cork harbour.

100 years ago this week, just before shipping was made safer by the entry of the United States into World War I, a number of Cork vessels were sunk by German U-boats and mines. Patrick G O’Shea recalls one of the lost ships, on which a relative was killed.
