“Courage is resistance to fear, mastery of fear – not absence of fear.” - Mark Twain
“Courage is fear holding on a minute longer.” Gen. George S Patton
Patton was an ass. A very successful ass, but an ass nonetheless. Pistol whipping your soldiers who have been driven mad by a concentrated prolonged artillery barrage is not cool.
I would point out that the British survivors of Operation Chariot, the Commando raid on the drydock at Saint-Nazaire, either quoted Mark Twain directly or paraphrased him when asked about it their courage and fear. They knew the operation was likely to be a one way trip and they still all volunteered. They rejected Patton’s view when questioned.
