Endurance

The Kaiser crushed the Belgians, French, and Dutch;
the Tzar groped towards the exit of this war.
A world away, one captain's out of touch,
ice-bound and drifting farther from the shore.
To lead in combat takes both skill and nerve,
and some part--we conjecture--is innate.
Unsatisfied in peace, each chose to serve
unknowing what adventure'd be their fate.
The purpose missing in so many lives
is not revealed in stars, or dice, or cards
Not individuals, but teams survive,
when challenges are other-worldly hard.
His ship's a loss, but with all personnel
Sir Ernest Shackleton walked back from Hell.
