At the end of October, 1941, the Destroyer Ruben James became the first american warship torpedoed by the Germans. She was escorting a Lend-lease convoy and met her end in a few seconds on a cold night off the coast of Ireland. The US didn't enter the war until Dec 8th, but when the 'Rube' went down, America began to understand there would be no avoiding the war in Europe.
Ruben James
Woodie Guthrie
    Have you heard of a ship called the good Reuben James
    Manned by hard fighting men both of honor and fame?
    She flew the Stars and Stripes of the land of the free
    But tonight she's in her grave at the bottom of the sea.
    CHORUS:
    Tell me what were their names, tell me what were their names,
    Did you have a friend on the good Reuben James?
    One hundred men were drowned in that dark watery grave
    When that good ship went down only forty-four were saved.
    'Twas the last day of October we saved the forty-four
    From the cold icy waters off that cold Iceland shore.
    It was there in the dark of that uncertain night
    That we watched for the U-boats and waited for a fight.
    Then a whine and a rock and a great explosion roared
    And they laid the Reuben James on that cold ocean floor.
    Now tonight there are lights in our country so bright
    In the farms and in the cities they are telling of the fight.
    And now our mighty battleships will steam the bounding main
    And remember the name of that good Reuben James.
