The Dapeng Brigade, originated in the Dapeng City of the Dapeng Bay in Guangdong, was moved to the Walled City in 1839 under the mandate of Lin Zexu. The whole troop was promoted from the rank of “camp” to that of “brigade”, with the Commodore, who received orders directly from the commander-in-chief of the Guangdong Navy, being the chief.
