Joint Anglo-Burgundian military operations had already begun. While the Burgundians had no objection as Burgundians to capturing and besieging Armagnac strongholds in northern France, as Frenchmen they disliked intensely the English practice of massacring or taking prisoner Armagnacs who had surrendered only after Burgundians had offered them life and a safe-conduct. Yet somehow the uneasy alliance survived, and even prospered. The two armies captured many towns and cities – among them Rheims, where the kings of France were traditionally crowned.It was essential for Henry and Philip to obtain the support and co-operation of Charles’s queen, Isabeau of Bavaria, who claimed to be Regent of France. Fat and fortyish – she had been born in 1379 – at her court in Troyes she surrounded herself, as she had always done, with gigolos and a menagerie including leopards, cats, dogs, monkeys, swans, owls and turtle doves. Despite having given her husband twelve children she was notoriously promiscuous.
