Captain’s Quarters quotes from the The Voyage of Earendil, which describes the capture of Morgoth, the renegade Valar responsible for much mayhem in the First Age:

… and all of the pits of Morgoth were broken and unroofed, and the might of the Valar descended into the deeps of the earth. There Morgoth stood at last at bay, and yet unvaliant. He fled into the deepest of his mines, and sued for peace and pardon; but his feet were hewn from under him, and he was hurled upon his face. Then he was bound with the chain Angainor which he had worn aforetime, and his iron crown was beaten into a collar for his neck, and his head was bowed upon his knees.

I was reading this not one week ago, and was struck by the anticlimactic similarity of it as well. Captain’s Quarters continues:

Unvaliant, indeed … his sons died fighting, a tactically stupid thing to do but a mistake that only hastened their eventual fate. Saddam, who had vowed never to be taken alive, did not even draw the pistol he carried when he was caught, and instead surrendered meekly. The Valar thrust Morgoth “through the Door of Night beyond the Walls of the World, and into the Timeless Void”; I suspect the Iraqis have something similar in mind, if less literary and more literal.

Indeed.
