General Sir James Frankfort Manners Browne KCB (24 April 1823 – 6 December 1910), Colonel-Commandant of Royal Engineers, was an Anglo-Irish officer in the British Army.

His mother was Catherine Penelope (died 1858), daughter of Lodge Evans Morres, 1st Viscount Frankfort de Montmorency.

[1] After serving at Woolwich and in Ireland, Browne embarked for Halifax, Nova Scotia, in March 1845, and on 1 April was promoted to lieutenant.

Browne took two months to reach the inaccessible spot now known as Winnipeg, and was engaged in surveying, superintending the clearance of forest, and pioneer work generally.

On reaching Balaclava on 5 February, Browne and his company were soon moved to the trenches of the British right attack on Sevastopol, and remained there until near the end of August.

Captain (afterwards Field-marshal Viscount) Wolseley of the 90th Foot was his assistant engineer, and Browne reported in high terms of his conduct.

[3] When Lieutenant-colonel Richard Tylden, of the Royal Engineers, director of the right attack, was fatally wounded on 18 June 1855, his duties devolved on Browne.

[3]On 1 January 1876 Browne was appointed colonel on the staff, and Commanding Royal Engineer of the South-Eastern District, with his headquarters at Dover; but his promotion to be major-general on 2 October 1877 (afterwards antedated to 22 February 1870) placed him on the half-pay list.
