A usually oval formation of several ranks of spearmen presenting a hedge of spear points to any attacker. (Wise, Terence. Medieval Warfare, 249) Related terms: Schiltron
a solid defensive arrangement with Pawns on the third rank e.g. Pb6,c5,d6,e6,g6, Bb7, Nbd7, Ngf6 and Be7 or Bg7. There is a comment on the potential of this formation under Nunn-Olafsson in the Planning section of the Canon, and an example game Webb-Hartston elsewhere in the Canon.
