Theo Metcalfe

Sir Theophilus John Metcalfe, 5th Baronet (1828–1883) was a British Bengal civil servant of the East India Company.

In 1849, the Treaty of Lahore transferred possession of the Koh-i-Noor diamond from Maharaja Duleep Singh to Governor-General Lord Dalhousie.

[3] After interviewing courtiers, jewelers, and local gossips he drafted a report about which he said, "I cannot but regret that the results are so very meagre and imperfect".

On the morning of 11 May 1857 he brought information to Delhi that Meerut mutineers of the previous day were crossing the river to the city.

[1] At Delhi Metcalfe led the cavalry that attacked the rebels' rear at the Battle of Najafgarh, and, during the assault of 14 September, guided George Campbell, with the 52nd light infantry, in the street fighting.

[1] Metcalfe married: first, in 1851, Charlotte, daughter of Sir John Low, died at Simla in 1853, leaving one child, Sir Charles Herbert Theophilus Metcalfe, 6th Baronet (1853–1928), a civil engineer; and secondly, in 1876, Katherine Hawkins, daughter of James Whitehead Dempster of Dunnichen, Forfarshire.
