Napoleonic Wars

Can I also just add, in terms of the peninsula, a couple of specifics that will happen in 1811 and 1812, unless the alt-history affects the outcome of the Napoleonic or Peninsular Wars.

@Athena Peters these could be good dates to know, if you're not already tracking them:

May 16, 1811 -- Battle of Albuera. The bloodiest of the entire Peninsular conflict. The French start with 24,000 troops, suffer ~8,000 casualties, representing a 33% loss. The British & Allies start with 35,000 troops, suffer ~7,000 casualties and about 1,000 additional troops taken prisoner, representing a 22% loss. The British "win." By which I mean, Wellington reports a win even though it is basically a bloodbath stalemate.

Wellington did manage to partially lift the "second" Siege of Badajoz during Albuera. But Badajoz remains under siege through 1812, by which time the Peninsular War becomes the Napoleonic War. This "third" siege of Badajoz ends badly for the French, but the Allies lose nearly 5,000 troops in the span of a few hours to break the Badajoz defense. When the (mostly English) troops finally enter Badajoz on 6 April 1812, they go on a rampage. It takes command *days* to bring the troops back under control. They smash homes, assault civilians, loot, drink, and leave 300 civilians dead in their wake. That was 20-30% of the whole town's population.

It is, by and far, one of the greatest wartime tragedies of either campaign.
