Cornet William Henry Field 

The 8th Hussars were in India at the time, following their service during the Mutiny.
It doesn't seem that Cornet Field joined them - he is known to have followed the course at the School of musketry in Hythe, and the following year :
"London Gazette, 2d December, 1862.
CAVALRY DEPOT (Canterbury) Cornet William Henry Field, of the 8th Hussars, to be Instructor of Musketry, vice Cornet Arthur Brett, of the 2nd Dragoon Guards, who has been ordered to join the Head Quarters of his Regiment. Dated 11th November, 1862."

 The 8th Hussars left India in early 1864, gathering dismounted at Brighton until mid-June, before taking over the troops horses and saddlery of the 18th Hussars and proceeding to York, where the Regiment was joined by the depôt troop from Canterbury.

That's the moment Field joined his regiment :
"London Gazette, 23rd August, 1864.
8th Regiment of Hussars, Cornet William Henry Field to be Instructor of Musketry, vice Lieutenant Edward Pulleyne, who has exchanged into the 18th Hussars.  Dated 9th August, 1864."

William Henry Field was promoted to Lieutenant on July 10th, 1866.
He must have been a proud Instructor, when The Times published, on February 28th, 1867 :
"The Adjt.-General Lord William Paulet, by order of the Field-Marshal Commanding-in-Chief, promulgated in a General Order, dated Horse Guards, 22d inst., the annual return showing the corps serving in the United Kingdom, the Channel Islands, North America and at the Mauritius which have completed the annual musketry course for 1866-7, with their figure of merit, &c. (...)
The following are the corps enumerated in the report, with the figure of merit :-
Cavalry.- 8th Hussars, 35.28 ; 3d Hussars, 30.77 ; 15th Hussars, 29.3 ; 10th Hussars, 28.35 ; 2d Dragoons Guards, 28.51 ; th Dragoon Guards, 27.42 ; 4th Hussars, 27.08 ; 5th Dragoon Guards, 22.07.
(...)"

The appointment of Instructor of Musketry does not appear anymore from the 1868 Army Lists on.
In the summer of 1869 the 8th Hussars went to Ireland. That's when William Henry Field gained his next rank :
"London Gazette, 6th July, 1869.
8th Hussars, Lieutenant William Henry Field to be Captain, by purchase, vice Henry Crawley Norris, who retires. Dated 7th July, 1869."

The regiment came back to England in 1875.
It seems that there was still much of the Instructor in Captain Field, as reported by The Times on June 5th, 1876 :
"Lieut.-Gen. Sir THomas Steele, K.C.B., commanding at Aldershott, having examined the reconnaissance reports and sketches of the officers and non-commissioned officers of the Cavalry and 2d Infantry Brigades executed during the past winter, hasexpressed his appreciation of the manner in which Capts. Schwabe and Provost, Brigade Majors, have voluntarily, in addition to their own duties, carried on the instruction of their respective brigades, and also of the zeal evinced by the following officers in assisting the efforts of Capt. Schwabe to impart instruction to the non-commissioned officers and men of their respective regiments :- Lieut. and Adj.Bell, 5th Lancers ; Capt. Field, 8th Hussars ; Lieut. and Adjt. Lloyd, 21st Hussars. (...)"

In 1878, a more personal event would be reported by The Times :
"BIRTH.
On the 7th June, at The Elas, Isleworth, the wife of Capt. FIELD, 8th Hussars, of a son."

By the end of the year the 8th Hussars would proceed to India - they would take part in the Second Anglo-Afghan War. Captain Field was not among them, as stated by the History of the VIII King's Royal Irish Hussars :
"The depôt, consisting of 6 officers and 89 non-commissioned officers and men under Captain Field, remained at Shorncliffe for the purpose of habding over the horses and saddlery to the 4th Hussars, and joined the cavalry depôt at Canterbury on the 10h of January, 1879. (...)
Captain Field had previously served with the depôt, and there were with him Captain Saunders, Lieutenants Davidson and Grant, and Second-Lieutenants Holmes and Wright."

Capt. Field would proceed to India in 1881, boarding the Troopship Malabar at Portsmouth on March 3rd, and leaving the next morning. The Malabar left Suez on the 19th inst., and reached Bombay on April 1st. The regiment was then quartered at Rawal Pindi, and one must wonder wether Captain Field made it in time to be present at the annual inspection that took place on the 7th, 8th and 9th April 1881, by Lieutenant-General sir M.A.Biddulph, K.C.B.

A few months later, the Royal Warrant of the 25th of June would affect the establishment of the regiment, instating :
-2 Lieutenant-Colonels instead of 1
-3 Majors  instead of 1
-4 Captains instead of 7
The London Gazette duly published on July 26th the promotion of Captain Field to the rank of Major (dated July 1st).

It appears that he was soon thereafter promoted to the rank of Lieutenant-Colonel, as the London Gazette would publish :
"London Gazette, 9th June, 1882.
8th Hussars, Lieutenant-Colonel Henry Langtry, from the 15th Hussars, to be Lieutenant-Colonel, vice W.H.Field, who exchanges.
Dated 10th June, 1882."

The 15th Hussars had come back the year before from Natal to England and Shorncliffe.
Lieutenant-Colonel Field would be in command of the regiment two years later :
"London Gazette, 27th May, 1884.
15th Hussars, Lieutenant-Colonel William Henry Field has been appointed to command the Regiment.
Dated 29th April, 1884."

Lieutenant-Colonel Field was appointed a member of the "Dress and Equipment Committee" in June 1884.
He was presented by the Adjutant-General to the Prince of Wales at the Levée held at St. James's Palace on March 14th, 1885, "on appointment to command of 15th Hussars".

His regiment was inspected by the Duke of Cambridge at Hounslow on July 11th, 1885, as reported by The Times :
"(...) The Duke of Cambridge and staff arrived shortly before 10 o'clock, and were received byMajor-General Gripps, C.B., commanding the Home District, and at once rode to Hounslow-heath, where the 15th (King's) Hussars, a regiment which took part in the Afghanistan campaign of 1878-80, was formed up in line of squadrons for inspection. Lieut.-Col. W.H.Field was in command. At the close of the work, which lasted nearly two hours, column was reformed, and the Duke of Cambridge, addressing the regiment, said he was extremely pleased with the smart turn out, work, and condition of Colonel Field's command, and congratulated that officer on the result of the inspection, which was in every respect most creditable. (...)"

He was gazetted to the rank of Colonel on October 6th, 1885 (dated 29th September), and would command the regiment for two more years :
"London Gazette, 15th July, 1887.
15th Hussars, Lieutenant-Colonel and Colonel William Henry Field, having completed his period of service as a Regimental Lieutenant-Colonel, has been placed on half-pay. Dated 1st July, 1887."

Five years later, a "Memorandum" published in the London Gazette on July 1st, 1892, stated that :
"Col. William H. Field, from Lieutenant-Colonel half-pay, is placed on retired pay."

His death was announced in The Times on April 18th, 1899 :
"DEATHS.
FIELD- On the 14th April, at Trelana, Stratton, N.Cornwall, COLONEL W.H.FIELD, late 8th Hussars and 15th Hussars, aged 58. No flowers."

His younger daughter Beatrice Kathleen Field was to marry Lieutenant A.D.Barrow, R.N., in September 1908.
His son William Robert Field married Dorothy Mildred on the 28th of April 1914.

"257. ARCHIBALD FERGUSON (18), Stealing a horse-roller, the goods of Colonel Field. 
MR. WILMOTT Prosecuted. 
THOMAS BELL. I am a private in the 15th Hussars and servant to Colonel Field—on the afternoon of the 17th, in consequence of something the stable-boy told me I went to the stable — I missed a horse-roller, Colonel Field’s property—I had seen the prisoner in the morning in the barracks —I gave information to the police who went in search of the prisoner— we met him on the road coming back—the constable told him to undo his coat, , and this roller of Colonel Field's fell down — he said nothing —I had last seen it safe about 2.29 —we did not see it until he unbuttoned his coat. 
DANIEL PALMER (Inspector T). About 3.30 pm, in consequence of information, I drove in a cab to the Isleworth Station, Bull following me on foot—I overtook the prisoner walking towards Brentford, carrying a parcel in his hand—I asked him what he had got in his hand, I did not then know what had been stolen, he said " Books"—I asked him where be got them, he said off a stall at Brentford—I said " Come back with me"—we got to Bull two minutes afterwards; I asked him what he had lost, he said " A horse-roller"—I undid the prisoner's coat and saw the roller—I said " You will be charged with stealing this from the barracks " —he said "I have not been to the barracks, I gave a shilling for it. "
Cross examined by the prisoner. After you were remanded you said that if I inquired of Palmer he would say he had seen a man give it to you—I have a letter from Palmer saying you did not ask him about it—(...). 
JOHN BUNKIN (Not examined in chief). Cross-examined. I saw you take this roller from the stable ; I saw the end of it —I was close to the stable door —I did not give you the roller to take to Isleworth Station —I did not give you a shilling. 
GUILTY. He then PLEADED GUILTY to a conviction of felony in (...), 1883.—Five Years' Penal Servitude. There was another indictment against the prisoner.""

We have here a superb view of the regimental pattern Busby and Sabretache, as well as the design of the pouch belt, adorned with the distinctive shamrocks of the King's Royal Irish Hussars.

It is a quite odd to see his belt worn over the tunic - most likely to smarten a little the somewhat loose jacket introduced after the Crimean War. No doubt the Dress and Equipment Committee he would join in 1884 would have strongly opposed that liberty taken with regulations !
