From Pepys' Diary, 17 January 1668:

Up, and by coach to Whitehall to attend the Council there; and here I met all the discourse of the duel yesterday between the Duke of Buckhingham, Holmes, and one Jenkins on one side, and my Lord of Shrewsbury, Sir Jo. Talbot, and one Bernard Howard, on the other side; and all about my Lady Shrewsbury, who is a whore and is at this time, and hath for a great while been a whore to the Duke of Buckingham; and so her husband challenged him, and they met yesterday in a close near Barne Elmes and there fought; and my Lord Shrewsbury is run through the body from the right breast through the shoulder, and Sir Jo. Talbot all along up one of his arms, and Jenkins killed upon the place, and the rest all in a little measure wounded. This will make the world think that the King hath good councillors about him, when the Duke of Buckingham, the greatest man about him, is a fellow of no more sobriety than to fight about a whore.
