The American rebellion by Rudyard Kipling

Twas not while England’s sword unsheathed
Put half a world to flight,
Nor while their new-built cities breathed
Secure behind her might
Not while she poured from Pole to Line
Treasure and ships and men –
These worshippers at Freedom’s shrine,
They did not quit her then!

Not till their foes were driven forth
By England o’er the main –
Not till the Frenchman from the North
Had gone with shattered Spain
Not till the clean-swept oceans showed
No hostile flag unrolled
Did they remember what they owed
To Freedom – and were bold!
