ANZAC COVE
Poem by Leon Gellert

There's a lonely stretch of hillocks:
There's a beach asleep and drear:
There's a battered broken fort beside the sea.
There are sunken trampled graves:
And a little rotting pier:
And winding paths that wind unceasingly.

There's a torn and silent valley:
There's a tiny rivulet
With some blood upon the stones beside its mouth.
There are lines of buried bones:
There's an unpaid waiting debt:
There's a sound of gentle sobbing in the South.
