It's a bit long-winded but below is a series of newspaper articles referencing the Harty Battery. From them it is possible to establish a timeline for the battery, an idea of what buildings were erected and when, and the strategic thinking behind the location chosen for the battery.
[b]Kentish Chronicle - Saturday 10 December 1859[/b]
Faversham - A battery for 2 guns is to be forthwith erected near Harty Ferry, the spot selected having been approved by the Government Inspector. Nearly £400 is already subscribed towards the maintenance of the Artillery- Corps, and a Rifle Corps is in course of formation. The Artillery will meet for drilling this Saturday evening in the Town Hall.

The spot selected for the battery is directly opposite the Coast-guard Station, Harty Ferry, the land for which has been measured and marked out a surveyor appointed for that purpose during the past week in order to fix its price. This being done, the battery will be proceeded with at once. It is, however, stated that the captain has determined upon erecting a temporary battery near his residence for practice purposes until the other is completed.

The Artillery Battery — Tuesday last. Colonel Williams, of the Royal Engineers, Chatham, came here for the purpose of marking out the site for the battery, which is to be erected for our gallant volunteers. He was accompanied to the spot at Harty-ferry by Major Munn, and with the assistance of that gentleman, “two-gun battery*' was marked out. This battery, it seems, is to be built out of the funds belonging (or rather to be provided by) the corps. As soon as the purchase of the land is complete, the platforms will, laid and small magazine erected, which, however, is to be at the Government expense. A sergeant of engineers is, we understand, to be sent to assist in constructing the battery and laying the platforms.

FAVERSHAM. 2nd Kent Artillery Coups. —The 2nd Battery belonging to this corps marched to Harty Ferry battery on Saturday last, and had some excellent ball practice during the afternoon. Several shots struck the target, one at length cutting away the mooring, letting the target free.

The Artillery Volunteers. —Our local volunteer force met on Saturday evening for their usual drill. Captain Hall has been promoted major-commandant. This appointment will give general satisfaction, and will be hailed by all as an appropriate end well-merited acknowledgment of the invaluable services that gentleman has rendered to the volunteer movement in this neighbourhood. It will be recollected that the two-gun battery at Harty Ferry was formed mainly through his munificent aid, and that he likewise erected temporary battery on his own premises nearer the town for the convenience of the members, fitted up building as an armoury, and converted the school-room at Stonebridge into drill-room The corps, however, cannot but regret that the promotion will greatly interfere with his presence amongst them.

Inspection of the Artillery Corps. The annual inspection of the 2nd Kent Artillery Corps took place at I the Harty Battery on Saturday afternoon week, by Colonel Elwyn, R.A., Dover. The muster was only moderately numerous, but all the officers were present," viz. Colonel I Gladdish, Captain and Adjutant McKown, Captain-Commandant Bathurst, Captain Shepherd, Lieut Hall, Lieut, Whittle and Hon. Assistant-surgeon, Dr. Spyers. The I corps, having marched past, went through the manual and platoon exercises, and company drill, 1 bey then tired ten rounds from the 32-pounder guns, and "five from the mortar. The gun practice was exceedingly good, one shot carrying away the flag from off the "target. At the close the inspection Col. Elwyn addressed the corps. said he did know of any corps that came up to them in the way in which they performed their manual exercise, and general efficiency, but they were not quite so smart the guns as they might be, which perhaps, arose from their taking more time in their anxiety to do well. They were, however, a most efficient corps, and it would afford him much pleasure to report to that effect the War Office. The officers afterwards dined with Major Hall at Syndale.

On the 13th instant, the Faversham Artillery Corps met at the Harty Ferry Battery for great gun and mortar practice in the presence of Colonel Chermside, R.A., the Inspector of Artillery Volunteers for the South-Eastern District. The Adjutant of the lst Administrative Brigade (Captain McKown) was also present, and the officers of the corps in attendance were Captain Commandant Shepherd, Lieutenant Whittle, Lieutenant Murton-Neale, and the Assistant Surgeon, Dr. Spyers. The new sixty-four pounder rifled muzzle-loading gun was used on this occasion for the first time. From it fifteen shells were fired, nine of which were plugged, two were charged with sufficient powder to burst them, and the remaining four had only "blowing charges" them. Several of the non-exploded shell have since been recovered; and to give an idea of the force of this new piece of ordnance we may state that some of them were picked up nearly opposite to the Sportsman's Arms at Seasalter. There were also nine shells fired from one of the old thirty-two pounders, with good execution, the target being hit several times, after which twenty rounds were fired with the mortar. The practice throughout was very good, and Colonel Chermside expressed himself perfectly satisfied.

New Magazine for the 2nd K.A.V. —We are glad to learn that the difficulty which the 2nd Kent Artillery Volunteers have for some time past experienced in regard to big gun practice owing to the fact of Major Majendie having condemned the building which had hitherto been used as a magazine, will shortly be overcome, the War Office authorities having, on the recommendation of Colonel Barry, and Colonel Sim, of the Royal Engineers, decided to erect a new magazine at Harty Ferry Battery. The work has already been commenced, Messrs. Foord and Son, Rochester, having taken the contract. It will be brick building, and will stand parallel with the present gun shed on the opposite side of the Battery.
