Been going through some more old History Channel docs as part of keeping the COVID isolation at bay, and the most recent was the Battlefield Detectives episode on the 1415 Battle of Agincourt, which goes in-depth into how terrain, weather, crowd control failure, and the French abandoning their sensible battle plan out of overconfidence/a focus on fighting only the English knights while ignoring the longbowmen all combined to produce an English victory, rather than the legendary "arrow storm". Leaving aside all this for the moment, given the numbers and types of the armies involved, what would've had to go differently for the French to win, or at the very least for Henry V to return to England in defeat or just something other than OTL's triumph?
