German field marshal (1891-1944)
Erwin Johannes Eugen Rommel (15 November 1891 – 14 October 1944) was a German Field Marshal and commander of the Deutsches Afrika Korps in World War II, widely referred to as The Desert Fox (Der Wüstenfuchs). Linked to a conspiracy to assassinate Adolf Hitler, he was ordered to commit suicide with a cyanide pill, in return for assurances that his family would not be persecuted following his death.

Be an example to your men in your duty and in private life. Never spare yourself, and let the troops see that you don't, in your endurance of fatigue and privation. Always be tactful and well-mannered and teach your subordinates to be the same. Avoid excessive sharpness or harshness of voice, which usually indicates the man who has shortcomings of his own to hide.
