Thomas Mullins (died 1823) was a British Army officer of the 44th Regiment of Foot, best known for his misconduct at the Battle of New Orleans during the War of 1812.
While he performed well during the Chesapeake campaign, his failure to check on the regiment's engineering supplies at New Orleans played a key role in the disorganization and subsequent defeat of the British there.
Mullins was also commended for his conduct during the Battle of North Point by Brooke, who succeeded Ross when the latter fell to a skirmisher's bullet.
The 44th was assigned by General Edward Pakenham to be the advance guard for the first column of attack on 8 January 1815, and to carry the ladders and fascines which would enable the British troops to cross the ditch and scale the American ramparts.
The other regiments were already advancing behind the 44th, the party of 300 lost formation as they struggled to reach the redoubt, and as day dawned, the attack commenced before the supplies could be brought forward.
The British attacks on the east side of the Mississippi River failed in bloody confusion, with Pakenham and Gibbs among the casualties.
