The 'Well Armed Men' The term used by Jan Dlugosz to describe some 6,000 infantry present at Tannenberg. They appear to have been a mix of armoured spearmen and Crossbowmen and were led by Brethren Officers. These units like their mounted counterparts were a mix of Mercenaries, Order foot, Vassal foot and City militias. They probably differed little from their German counterparts. Surprisingly they appear to have been swept away by the first charge at Tannenberg.
