If Britain took the Philippines in the Napoleonic Wars

What if Britain captured the Philippines from Spain during the Napoleonic Wars?

The islands would likely remain a British imperial possession into the twentieth century, adding both regional influence and a new long-term defence commitment.

The answer sees British retention of the Philippines as plausible once the islands are taken during the Napoleonic Wars. They would add strategic depth around Australia and create a major new imperial commitment in East and Southeast Asia. By the Second World War the islands would therefore be defended as British territory rather than as an American commonwealth. Their later status would probably move toward decolonization, but through a different political path. An early successful seizure might also encourage Britain to intervene against neighbouring Dutch possessions, reshaping the region beyond the Philippines themselves.
