This really has been a well conducted and interesting thread. I was happy to contribute and to read what others had to say. A.L. Lloyd is said to have composed this hymn:

The Seamen's Hymn

Come all ye bold seamen, wherever you're bound,
And always let Nelson's proud memory go 'round;
And pray that the wars and the tumult may cease,
For the greatest of gifts is a sweet lasting peace;
May the Lord put an end to these cruel, old wars,
And bring peace and contentment to all our brave tars.
