Carte-de-Visite, studio R.Faulkner & Co in Bayswater

Henry Stephen Walker
Cornet in the 13th Hussars

This photograph is identified as displaying "Captain Thomas George Johnson".
Yet just too many things are wrong for this gentleman to be Thomas George Johnson.

Luckily the 13th Hussars spent part of the 1860s in Canada, where many of them were photographed by William Notman. A fantastic collection of Notman's photos is available thanks to the Musée McCord - including some of of this gentleman :

Robert Faulkner settled at the 46, Kensington Gardens Square, Westbourne Grove, Bayswater, W. London in 1864 (he'll stay there until 1877 when the studio moved).

The 13th Hussars will soon sail to Canada ; the Times of September 13th 1866 relates :
"The Cunard steamers Tarifa and Europa, which have been completely overhauled and refitted for the reception of the 13th Hussars, left the Mersey yesterday at 2 p.m. for Quebec.
The Tarifa has on board 13 officers, 182 men, and 172 horses. The officers are Lieut.-Col. Jenyns, C.B. ; Capts. Clarke, Innes, and Hill ; Lieuts Ford, Clay, and Webb ; Cornets Hamilton, Pole, and Ellis ; Lieut. and Adjt. Joyce, Surg. Armsrong, and Vet.-Surg. Varley. The Europa conveys 13 officers, 144 men, and 131 horses. The officers are Major Maclean ; Capts. Atkinson, Huddleston, and Miles ; Lieuts. Starkey, Higgins, and Horne ; Cornets Bieber and Moore ; Paymaster Frith, Riding-master Hubbard, Quartermaster Cresdee, and Assist.-Surg. Milburn. To-day, at 9a.m., the Allan steamer will go alongside the great landing-stage and take on board nine officers and 153 dismounted men of the same regiment, and detachments for other corps, to the number of about 240, and sail about noon. These vessels also take out several hundred tons of military stores."

Cornet Walker is not named among the officers - and it is possible that he sailed on board the Allan ; in any case, the Notman photographs testify that he went to Canada.

The Regiment had been sent to Canada following the unrest due to the Fenian activists (mostly demobilized soldiers of Irish extract, fighting the British presence in Canada), trouble that led the Governor general to request Regular Cavalry troops - the lack of which had been exposed in the previous operations.
The 13th Hussars will be mainly quartered in Toronto (Fort York).
During their tour, they will open a School of Cavalry there, that will train local Cavalry Troops.
This will create a lasting heritage, as Canadian Cavalry regiments will adopt a uniform after that of the Regiment, a tunic of Hussar pattern with white facings (though most will sport pith helmets).

Henry Stephen Walker will purchase his Lieutenantcy on October 12th, 1867, "vice Harle".

The 13th Hussars will sail back to England in August 1869 ; The Times relates, on August 14th : "Yesterday the troopship Simoom arrived in the Mersey from Quebec, and landed the 13th Hussars, consisting of 19 officers, 7 officers' wives, and 10 officers' children, 403 men, 71 women, and 103 children. In the course of the day the troops left for York, and the Simoom at once proceeded to take on board the 15th Hussars, from York, and will take them round to Portsmouth, en route for Chichester, whence they will shortly leave for India."

Henry Stephen Walker will not take part in those further travels, as the London Gazette will soon announce :
"13th Hussars, Cornet Athelstane Robetr Pryce to be Lieutenant, by purchase, vice Henry Stephen Walker, who retires. Dated 8th June, 1870."
