Colonel Thomas Cadell VC CB (5 September 1835 – 6 April 1919) was an army officer who served in India.

He served during the 1857 rebellion and was a Scottish recipient of the Victoria Cross, the highest and most prestigious award for gallantry in the face of the enemy that can be awarded to British and Commonwealth forces.

Cadell was 21 years old and a lieutenant in the 2nd European Bengal Fusiliers (later The Royal Munster Fusiliers) during the Indian Mutiny when he performed the deeds on 12 June 1857 at Delhi, India which resulted in being awarded the Victoria Cross: For having, on the 12th of June, 1857, at the Flag-staff Picquet at Delhi, when the whole of the Picquet of Her Majesty's 75th Regiment and 2nd European Bengal Fusiliers were driven in by a large body of the enemy, brought in from amongst the enemy a wounded Bugler of his own regiment, under a most severe fire, who would otherwise have been cut up by the rebels.

Also, on the same day, when the Fusiliers were retiring, by order, on Metcalfe's house, on its being reported that there was a wounded man left behind, Lieutenant Cadell went back of his own accord towards the enemy, accompanied by three men, and brought in a man of the 75th Regiment, who was severely wounded, under a most heavy fire from the advancing enemy.

[2]Cadell later achieved the rank of colonel in the service of the Indian Staff Corps and held various political appointments in India.
