A. P. Herbert - Broken Glass

The house still stands: but Hitler has had five shots.
The glass, the maddening glass, is everywhere.
We still are gathering glass and forget-me-nots.
We still are growing glass where the roses were.
Each little piece I pluck from a flowerbed
Is a piece of Hitler, soiling the English spring.
For each I cry a curse on a German head,
And when I remember Aachen—I laugh and sing.
April 5, 1945
