Eighty years have passed, and more,
Since under the brave old tree
Our fathers gathered in arms, and swore
They would follow the sign their banners bore,
And fight till the land was free.
Half of their work was done,
Half is left to do,—
Cambridge, and Concord, and Lexington!
When the battle is fought and won,
What should be told of you?
Hark! — 'tis the south-wind moans, —
Who are the martyrs down?
Ah, the marrow was true in your children's bones
That sprinkled with blood the cursed stones
Of the murder-haunted town!
What if the storm-clouds blow?
What if the green leaves fall?
Better the crashing tempest's throe
Than the army of worms that gnawed below;
Trample them one and all!
Then, when the battle is won,
And the land from traitors free,
Our children shall tell of the strife begun
When Liberty's second April sun
Was bright on our brave old tree!
In its own way, the poem is somewhat like "Paul Revere's Ride" in that it discusses a Revolutionary War topic in the context of the Civil War ("the south wind moans"). Earlier in the month when Holmes wrote it, his son Oliver Wendell Holmes, Jr. enlisted in the Union Army.
The tree no longer stands; when it became old it was torn down (and cut into souvenir pieces). There is no significant proof of the connection to Washington. Even so, a marker exists (shaped innocuously like a manhole cover) in the street in the middle of one of the most dangerous intersections in Cambridge (gawkers, beware).
