As quoted by Philibert de Gramont (1701), in Memoirs of the Court of Charles the Second (1846) by Anthony Hamilton, edited by Sir Walter Scott.
Context: Mrs. Lane and I took our journey towards Bristol, resolving to lie at a place called Long Marson, in the vale of Esham.
But we had not gone two hours on our way but the mare I rode on cast a shoe; so we were forced to ride to get another shoe at a scattering village, whose name begins with something like Long—. And as I was holding my horse's foot, I asked the smith what news? He told me that there was no news that he knew of, since the good news of the beating of the rogues the Scots. I asked him whether there was none of the English taken that joined with the Scots? He answered, that he did not hear that that rogue Charles Stewart was taken; but some of the others, he said, were taken, but not Charles Stewart. I told him, that if that rogue were taken he deserved to be hanged, more than all the rest, for bringing in the Scots. Upon which he said, that I spoke like an honest man, and so we parted.

Context: 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.
