Final answer:
While there is no direct record of the fate of Jean de Joinville's horse during the battle, historical comparisons suggest that horses in warfare often faced the possibility of injury or death.
Step-by-step explanation:
The fate of Jean de Joinville's horse during the battle is not directly recorded, but drawing parallels from similar historical accounts, it can be surmised that horses were crucial in warfare and often suffered injuries or deaths. For example, during the Battle of the Wilderness, General Braddock had several horses shot out from under him in a clash of European warfare tactics with the guerrilla style of the French and Indian troops. Similarly, in Napoleonic warfare, horses were emblematic of power and military prestige, as shown through equestrian portraits and battle paintings which illustrated both moments of glory and defeat for riders and their horses.
