Quatre Bras - Oportunidad perdida? (Spanish: "Quatre Bras - Lost oportunity ?") is a Spanish Wargame on the battle of Quatre Bras (16 June 1815). This is an hex-and-counter game that uses the Sombra del Águila (Shadow of the Eagle) system rules. The board hexes are numered as to facilitate the initial positioning of counters and victory points. The counters represent units, leaders, formations and events, and are printed so that could be glued and cut. The board and counter sheets are available with the spanish magazine Wargames; Soldados y Estratégias nº 46. Game System: - scale = 250m hex; - time = 20 min/GT; - strength = battaillons (inf), regiments (cav), batteries (art).
