Lieutenant-Colonel Sir Thomas St Vincent Hope Cochrane Troubridge, 3rd Baronet CB (25 May 1815 – 2 October 1867) was an officer of the British Army who served with distinction during the Crimean War.

He served with his regiment in many stations throughout the Empire, inheriting his father's baronetcy in 1852, and held the rank of major in 1854 when the Crimean War broke out.

He was involved in the heavy fighting surrounding the defense of British gun batteries during the Battle of Inkerman, and was badly wounded, losing his right leg and left foot.

[1][2] Meeting heavy resistance the Russians concentrated their forces against the battery, and in the desperate fighting that followed Troubridge was wounded by a shot which carried off his right leg and left foot.

He refused to be removed from the position, and remained at his post for the next two hours until the attack was beaten off, his limbs propped up on a gun carriage to prevent him from bleeding to death.

[2] In Lord Raglan's despatches of 11 November (gazetted on 2 December), Troubridge was Mentioned as having "behaved with the utmost gallantry and composure", despite his wounds.

[1][9] Troubridge was promoted to brevet lieutenant colonel on 12 December 1854 "for distinguished service in the Field",[10] but his injuries caused him to be invalidated home in May 1855.

[14] Troubridge received a substantive promotion to lieutenant-colonel (without purchase), and thus became the commanding officer of the Royal Fusiliers on 9 March 1855,[15] but his disability prevented him from serving with the regiment.
