In In the Midst of Alarms (1894) by Robert Barr, the author was describing the wife of a Canadian farmer:
As he rose the door from the main portion of the house opened, and there entered a woman hardly yet past middle age, who had once been undoubtedly handsome, but on whose worn and faded face was the look of patient weariness which so often is the result of a youth spent in helping a husband to overcome the stumpy stubbornness of an American bush farm. When the farm is conquered, the victor is usually vanquished. It needed no second glance to see that she was the mother from whom the daughter had inherited her good looks.
How could the victor be vanquished at the same time?
