The St. Crispin’s Day speech is a famous speech from William Shakespeare’s play, Henry V, in Act IV Scene iii 18–67.
On the morning of 25 October 1415, shortly before the Battle of Agincourt, Henry V made a brief speech to the English army under his command, emphasizing the justness of his claim to the French throne and harking back to the memory of previous defeats the English kings had inflicted on the French. According to Burgundian sources, he concluded the speech by telling the English longbowmen that the French had boasted that they would cut off two fingers from the right hand of every archer, so they could never draw a string again.

This day is called the feast of Crispian:
He that outlives this day and comes safe home,
Will stand a tip-toe when this day is named,
And rouse him at the name of Crispian.
He that shall live this day, and see old age,
Will yearly on the vigil feast his neighbours,
And say, ‘To-morrow is Saint Crispian:’
Then will he strip his sleeve and show his scars,
And say, ‘These wounds I had on Crispin’s day.’
Old men forget: yet all shall be forgot,
But he’ll remember with advantages
What feats he did that day. Then shall our names,
Familiar in his mouth as household words,
Harry the King, Bedford and Exeter,
Warwick and Talbot, Salisbury and Gloucester,
Be in their flowing cups freshly remembered.
This story shall the good man teach his son;
And Crispin Crispian shall ne’er go by,
From this day to the ending of the world,
But we in it shall be rememberèd;
We few, we happy few, we band of brothers;
For he to-day that sheds his blood with me
Shall be my brother; be he ne’er so vile
This day shall gentle his condition:
And gentlemen in England, now a-bed
Shall think themselves accursed they were not here,
And hold their manhoods cheap whiles any speaks
That fought with us upon Saint Crispin’s day.
