Listen my children and you shall hear
Of the midnight ride of Paul Revere,
On the eighteenth of April, in Seventy-five;
Hardly a man is now alive
5 Who remembers that famous day and year.

He said to his friend, "If the British march
By land or sea from the town to-night,
Hang a lantern aloft in the belfry arch
Of the North Church tower as a signal light,--
10 One if by land, and two if by sea;
And I on the opposite shore will be,
Ready to ride and spread the alarm
Through every Middlesex village and farm,
For the country folk to be up and to arm."

15 Then he said "Good-night!" and with muffled oar
Silently rowed to the Charlestown shore,
Just as the moon rose over the bay,
Where swinging wide at her moorings lay
The Somerset, British man-of-war;
20 A phantom ship, with each mast and spar
Across the moon like a prison bar,
And a huge black hulk, that was magnified
By its own reflection in the tide.

Meanwhile, his friend through alley and street
25 Wanders and watches, with eager ears,
Till in the silence around him he hears
The muster of men at the barrack door,
The sound of arms, and the tramp of feet,
And the measured tread of the grenadiers,
30 Marching down to their boats on the shore.

Then he climbed the tower of the Old North Church,
By the wooden stairs, with stealthy tread,
To the belfry chamber overhead,
And startled the pigeons from their perch
35 On the sombre rafters, that round him made
Masses and moving shapes of shade,--
By the trembling ladder, steep and tall,
To the highest window in the wall,
Where he paused to listen and look down
40 A moment on the roofs of the town
And the moonlight flowing over all.

Paul Revere from Wikipedia
Between 9 and 10 p. m. on the night of April 18, 1775, Joseph Warren told Paul Revere and William Dawes that the king's troops were about to embark in boats from Boston bound for Cambridge and the road to Lexington and Concord. Warren's intelligence suggested that the most likely objectives of the regulars' movements later that night would be the capture of Samuel Adams and John Hancock. They did not worry about the possibility of regulars marching to Concord, since the supplies at Concord were safe, but they did think their leaders in Lexington were unaware of the potential danger that night. Revere and Dawes were sent out to warn them and to alert colonial militias in nearby towns.

In the days before April 18, Revere had instructed Robert Newman, the sexton of the North Church, to send a signal by lantern to alert colonists in Charlestown as to the movements of the troops when the information became known. In what is well known today by the phrase "one if by land, two if by sea", one lantern in the steeple would signal the army's choice of the land route while two lanterns would signal the route "by water" across the Charles River (the movements would ultimately take the water route, and therefore two lanterns were placed in the steeple). Revere first gave instructions to send the signal to Charlestown. He then crossed the Charles River by rowboat, slipping past the British warship HMS Somerset at anchor. Crossings were banned at that hour, but Revere safely landed in Charlestown and rode to Lexington, avoiding a British patrol and later warning almost every house along the route. The Charlestown colonists dispatched additional riders to the north.

Read the excerpt of Longfellow's poem "Paul Revere's Ride" and then the excerpt of the historical account of that same night from Wikipedia. Then in a well-written essay analyze how Longfellow's poem compares and contrasts with the facts from history.
