The Line of Love by James Branch Cabell

It was not long before they came upon d'Andreghen and his men camped about a great oak, with One-eyed Peire a-swing over their heads for a lamentable banner. A shrill sentinel, somewhere in the dark, demanded the newcomers' business, but without receiving any adequate answer, for at that moment Adhelmar gave the word to charge.

Then it was as if all the devils in Pandemonium had chosen Normandy for their playground; and what took place in the night no man saw for the darkness, so that I cannot tell you of it. Let it suffice that Adhelmar rode away before d'Andreghen had rubbed sleep well out of his eyes; and with Adhelmar were Hugues d'Arques and some half of Adhelmar's men. The rest were dead, and Adhelmar was badly hurt, for he had burst open his old wound and it was bleeding under his armor. Of this he said nothing.
