Thomas Wallace Knox (1835-1896) was a prodigious travel writer of the late nineteenth century. As a war correspondent for the New York Herald, he ran afoul of General Grant when he published information concerning troop locations, which Grant believed aided the enemy. Subsequently he was court-martialed for "giving intelligence to the enemy, " and of "being a spy". He was also the author of Camp-Fire and Cotton-Field: Southern Adventure in Time of War (1865) (an autobiographical text), Overland Through Asia: Pictures of Siberian, Chinese, and Tartar Life (1870), The Boy Travellers in the Far East (1879), Adventures of Two Youths in Siam and Java (1880), The Boy Travellers in Great Britain (1891) and Captain John Crane (1899).
