Read the poem about the Battle of Trenton and answer the question: "In Trenton when the sun was set,
The Hessians at their quarters met;
And while the brilliant candles shine,
They pass along the sparkling wine:
For Christmas day had come and gone,
The joyful hours were nearly flown;
With a merry laugh our country’s foe
Enjoy the minutes as they flow,
And many a soldier sang with glee
Of blue-eyed maids in Germany. _
On Pennsylvania’s wintry shore
The chilling blast howled loud and sore;
When lulled the winds, there echoed then
The heavy tramp of armed men.
Columbia’s sons haste to the strife,
To strike for liberty and life. -
George Washington was at their head!
A gallant band, and nobly led . . ." -
