Tale Of Two Cities
One of the squires in attendance upon the coach, a Biscayan, was listening to all Don Quixote was saying, and, perceiving that he would not allow the coach to go on, but was saying it must return at once to El Toboso, he made at him, and seizing his lance addressed him in bad Castilian and worse Biscayan after his fashion, "Begone, caballero, and ill go with thee; by the God that made me, unless thou quittest coach, slayest thee as art here a Biscayan."
The Biscayan, when he saw him coming on, though he wished to dismount from his mule, in which, being one of those sorry ones let out for hire, he had no confidence, had no choice but to draw his sword; it was lucky for him, however, that he was near the coach, from which he was able to snatch a cushion that served him for a shield; and they went at one another as if they had been two mortal enemies.
