I wouldn't call two armies running into each other ouwitted, even if the spot they collided was more favorable to the other. And besides, we weren't even in command, and the actual Teutonic forces made up a small majority of the whole army. Mostly troublesome Livonian ex-Swordbrethren adventuring on grand schemes to conquer Estonia and plunge the Order into war with Denmark. That campaign was mostly an effort to do something at all with them...
