This battle is the first described in John Keegan’s The Face of Battle, which attempts to visualize wedges of soldiers in mixed-rank “hedgehog” formation. Ruth Bader Ginsburg judged a mock trial that condemned the victor of this battle for issuing an order to execute all prisoners when local peasants raided his unguarded baggage train. “Double subsidies” raised a fleet of up to 1,500 cogs for the winners of this battle, who attempted to retreat to (*) Calais after (10[1])taking heavy losses while besieging Harfleur. This battle, the climax of an invasion allegedly launched as a reaction to a gift of tennis balls, ended when mounted men-at-arms under Charles D’Albret charged through mud on Saint Crispin’s Day, only to be massacred by longbows. For 10 points, name this 1415 battle, a victory for Henry V. ■END■
