[1] Gibbs was second-in-command under Edward Pakenham at the Battle of New Orleans and died of wounds received while leading one of the main columns in the failed British assault.

[1] On 25 July 1810 he received the brevet rank of colonel, and in March 1811 accompanied the expedition under Sir Samuel Auchmuty, which was sent by Lord Minto to conquer Java from the Dutch.

[1][3][4] Shortly afterwards Gibbs left India, and in 1812 was appointed to the command of the two British regiments stationed with the allied (Coalition) forces at Stralsund.

In the autumn of 1814 he was appointed second in command under Sir Edward Pakenham of the expedition sent out to succour the British forces in the United States.

[1][7][8] He was heard yelling for his subordinate, "Colonel Mullens, if I live till tomorrow you shall be hanged from one of these trees",[b][9] whereupon he was shot from his horse, just fifty paces from Jackson's line.

[2] A marble free-standing monument with life-size effigies of Pakenham and Gibbs sculpted by Richard Westmacott was erected in St. Paul's Cathedral.
