Sigourney wrote regular poetry for the magazine “Atlantic Monthly”, and his poem, "The Dead" was published in numerous WW1 poetry anthologies.
“The Dead”
I feared the lonely dead, so old were they, --
Decrepit, tired beings, ghastly white,
With withered breasts and eyes devoid of sight,
Forever mute beneath the sodden clay;
I feared the lonely dead, and turned away
From thoughts of sombre death and endless night;
Thus, through the dismal hours I longed for light
To drive my utter hopelessness away.
But now my nights are filled with flowered dreams
Of singing warriors, beautiful and young;
Strong men and boys within whose eyes there gleams
The triumph song of worlds unknown, unsung;
Grim death has vanished, leaving in its stead
The shining glory of the living dead.
