Key passages

  • 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!

    You hypocritically claim to fight for free seas, yet your submarines have left a trail of destroyed ships and horror across every ocean.

    The speaker accuses Germany of hypocrisy, contrasting its stated war aims with its brutal submarine warfare.

  • 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 sent to drown.

    The countless spirits of those you murdered at sea condemn you; the sailors you abandoned now fashion a crown of shame for you from the deep, a grim reminder of the women and children you drowned.

    The poet invokes the ghosts of victims to shame Germany, emphasizing the killing of non-combatants.

  • 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!

    Only when thieves guard treasure, pirates protect trade, and wolves herd sheep will anyone trust you, ruthless tyrant of the sea, to uphold law and freedom.

    The speaker uses absurd analogies to argue that Germany is fundamentally untrustworthy to enforce maritime law.

  • 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.

    We place our faith in more honorable nations, where moral duty outweighs necessity and honor governs both peace and war. We stand with them in spirit and commitment until liberty is secure everywhere.

    The poem ends by affirming allegiance to allied nations that prioritize ethics and honor over brute force.
