Is there a pattern to the imagery in "Anthem for Doomed Youth"?

There is a progression of images in the poem, all having
to do with those who are left behind—family, sweethearts, parents. The “holy glimmers of
good-byes” suggests how light from altar candles shines in the tear-filled eyes of those
who mourn. The grief of sweethearts is suggested by the “pallor of girls’ brows.” The
consolations of philosophy and the privacy of grief are brought out by the “tenderness
of patient minds” and the “drawing-down of blinds.” All the images share in depicting
the unutterable grief of those whose loved ones are now dead.
