Great article over at The Art Of Manliness on the men in the Battle of the Alamo. I think the three section headings say it all:

• Never compromise your values. (I Corinthians 16:13, Ephesians 6:11, 13-14)
• A great man keeps company with great men. (Psalm 111:1, I Corinthians 15:33)
• Great men are courageous in the face of adversity. (Deuteronomy 31:6, John 16:33)
