Let the soldier be abroad if he will, he can do nothing in this age. There is another personage,- a personage less imposing in the eyes of some, perhaps insignificant. The schoolmaster is abroad, and I trust to him, armed with his primer, against the soldier in full military array.
A farmer, a hunter, a soldier, a reporter, even a philosopher, may be daunted; but nothing can deter a poet, for he is actuated by pure love. Who can predict his comings and goings? His business calls him out at all hours, even when doctors sleep.
One of George Washington's main concerns was to make sure that his soldiers had adequate supplies of meat: A part of the army has been a week without any kind of flesh, and the rest three or four days. Naked and starving as they are, we cannot enough admire the incomparable patience and fidelity of the soldiery, that they have not been ere this excited by their suffering to a general mutiny and dispersion.
To be a successful soldier you must know history. . . . What you must know is how man reacts. Weapons change but man who uses them changes not at all. To win battles you do not beat weapons - you beat the soul of man of the enemy man.
George Patton (1885 - 1945)
