Battle of Macau

The Battle of Macau in 1622 was a conflict of the Dutch-Portuguese War fought in the Portuguese settlement of Macau, in southeastern China. The Portuguese, outnumbered and without adequate fortification, managed to repel the Dutch in a much-celebrated victory on 24 June after a three-day battle. To date, the battle remains the only major engagement that was fought between two European powers on the Chinese mainland.
