Mare Liberum

You dare to say with perjured lips, 
    "We fight to make the ocean free"? 
You, whose black trail of butchered ships 
    Bestrews the bed of every sea 
    Where German submarines have wrought 
    Their horrors! Have you never thought,—
What you call freedom, men call piracy! 

Unnumbered ghosts that haunt the wave 
    Where you have murdered, cry you down; 
And seamen whom you would not save, 
    Weave now in weed-grown depths a crown 
    Of shame for your imperious head,—
    A dark memorial of the dead,—
Women and children whom you left to drown

Nay, not till thieves are set to guard 
    The gold, and corsairs called to keep 
O'er peaceful commerce watch and ward, 
    And wolves to herd the helpless sheep, 
    Shall men and women look to thee—
    Thou ruthless Old Man of the Sea—
To safeguard law and freedom on the deep! 

In nobler breeds we put our trust: 
    The nations in whose sacred lore 
The "Ought" stands out above the "Must," 
    And Honor rules in peace and war. 
    With these we hold in soul and heart, 
    With these we choose our lot and part, 
Till Liberty is safe on sea and shore.
