Germany throws out English sales people, 11th August, 1597

According to History Orb's site for today in history, and several other "this day in history" lists, English sales people were expelled from Germany on August 11th, 1597. This looked an interesting subject to write about, but I cannot find any more information on it...including the Today in German History site....(pause for short excursion into the excellent beer section of their site).
Maybe the Bad History blog carnival will be interested in this and can start a campaign for more research links to be provided from these one-liner sites.
