October 25 is the Feast Day of Saints Crispin and Crispian, twin brothers said to have been martyred for their belief. They were said to be leather workers; they are the patron saints of that craft.
The day is remembered more for the play by Shakespeare, Henry V, which contains one of the most famous declamations in all literature.
The speech is given before the Battle of Agincourt, 1415, where Henry's force of less than 200 men crushed the French force numbering in the thousands, affecting the course of European history for centuries:
This day is call'd 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.
Be in their flowing cups freshly rememb'red.
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 remembered-
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."
The newly "invented" long-bow, which owes its effectiveness to the unique characteristics the English Yew, was a decisive factor in the battle.
For historians this day also marks The Charge of the Light Brigade - for which the speech seems ironically fitting - and the Battle of Leyte Gulf, one of the critical naval battles of the WWII Pacific Theater.
From time to time it is helpful to recall these things.
