The Battle of Agincourt, when English longbowmen, though heavily outnumbered, stood their ground and defeated the French in the most lopsided victory of the Hundred Years' War.

The Battle off Samar, climax of the Battle of Leyte Gulf, when a heavily outclassed force of USN escort carriers, destroyers, and destroyer escorts drove off a Japanese force of battleships and heavy cruisers and saved the US landing on Leyte. The gallant charge of the destroyers was the bravest act of the war in the Pacific.

1975

The greatest baseball game ever played. “Game Six, Game Six … what can we say of it without seeming to diminish it by recapitulation or dull it with detail? Those of us who were there will remember it, as long as we have any baseball memory, and those who wanted to be there and were not will be sorry always. Crispin Crispian: for Red Sox fans, this was Agincourt.”—Roger Angell, Agincourt and After.

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.
