Last, the Prussian trumpet blew;
Thro’ the long-tormented air
Heaven flash’d a sudden jubilant ray,
And down we swept and charged and overthrew.
So great a soldier taught us there,
What long-enduring hearts could do
In that world’s earthquake, Waterloo!”
The best expression in it, the last, is borrowed from Byron’s wonderful description of the same battle:
“Stop! for thy tread is on an Empire’s dust!
An Earthquake’s spoil is sepulchred below!”
