Seen it before? No.
Kirk Douglas plays Col. Dax, a French army officer in World War I. The commanding officers order a suicidal attack on a German fortification, which fails, so they decide to court-martial and execute three randomly selected soldiers for cowardice. Dax is outraged by the arbitrary, unfair punishment, so he takes up the defense of the three soldiers.
There really aren't a whole lot of World War I movies, I suppose because it was so horrible, and there were no clear good guys or bad guys. This movie was banned in France, and you can see why; they make the generals out to be totally evil and sadistic. Of course that doesn't mean it was unrealistic.

The title: From Thomas Gray's "Elegy Written in a Country Churchyard":
The boast of heraldry, the pomp of pow'r,
And all that beauty, all that wealth e'er gave,
Awaits alike th'inevitable hour.
The paths of glory lead but to the grave.
