Boca Tigre

Boca Tigre, Bocca Tigris, or "The Bogue" (Chin. Hu-mun, tiger's mouth), a name of Portuguese origin given to the mouth of the Canton river known to the Chinese as Choo-Kiang or Pearl river. "The Outer Waters" or broad estuary extending southwards is blocked to some extent about 45 miles below Canton by five islands, all of which were strongly fortified to check any advance by water to Canton. The "Bogue" forts were captured by the British in 1841 and in 1856, and were completely dismantled.
