Whoops one more correction. The rifles weren't on the submarine, they were on the frieghter, Aud. The Submarine, (at first the U21 under Lut. Com. Walter Swieger, the boat that sank the Lusitania) developed engine troble and had to return to Germany, so Roger was late to arive in Tralee bay. Waiting on the shore was Morty O'Leary, (who's grnadson taught me to build currachs). Morty was to be the pilot for the Aud, but she kept giving the wrong signal. Morty knew it was the Aud, but was stuborn and off that beach he would not go, until he got the right signal. Meanwhile the six young lad who were to bring Morty the new signal had driven off Connor Pass and were killed in the crash. So, the HMS Otway (no kidding) spoted the Aud, and well the rest is history.
Just one more to say, thank god for cheep watches...
