Trees in the old days used to stand
And shape a shady lane
Where lovers wandered hand in hand
Who came from Carentan.
This was the shining green canal
Where we came two by two
Walking at combat-interval.
Such trees we never knew.
The day was early June, the ground
Was soft and bright with dew.
Far away the guns did sound,
But here the sky was blue.
