By 1834, the armament had been reduced to four 12-pounders and two 12-pounder carronades.
In 1841, Major General Sir John Jones’s Overall Plan for the improvement of the defences was highly critical of the deteriorated state of defence of the entire South Front writing:17
I am led to consider the Southern Defences more seriously than perhaps may have been thought necessary for some time past, I therefore beg to submit to your judgement whether it may not be expedient to re-establish Batteries in the Flanks of the Flat and Demi-Bastions so as to bring on some defence on the South Front, as also obstructions in the approach to the Gates.
His recommendation was as follows:18
Item 4. To cover the Magazine and repair and restore the parapet and communications, and put the South Front into perfect order.
This front, built by Charles V of Spain, is of obsolete construction but the masonry being good, and the escarpe walls lofty, I should not have proposed more than the restoration of the decayed and damaged communications, had not a magazine, constructed a few years since on the left or upper flank of Flat Bastion, opened the escarpe wall, destroyed the flank defence and rendered imperative some additional walling as well to enclose the place and prevent the destruction of the building. The parapet of Flat Bastion requires to be re-instated and prepared for artillery and the communications to be made more easy, and some scarping is required along the left where the flank abuts against the rock face. The portion of the wall ascending the heights on the left of Prince Edward's Gate is exposed to view from top to bottom, and the Glacis and covered way along the flat ground on the right are so faulty and neglected as to be almost defenceless, and the former is used as a depot for guns, shot and shell, and being overshadowed by trees the whole exterior has a most unmilitary appearance.
The ground in front of the Line, however, being so closely plunged down upon by artillery on the flanking heights as to preclude the possibility of an enemy establishing himself on the Glacis, I cannot recommend any expense being incurred for their reform; and further, as the depot is conveniently placed for the movement of stores at Ragged Staff, I am unwilling to propose any interference with the existing arrangements of the Storekeeper, The trees and shrubs both on the Glacis and in the ditch are objectionable as impeding the view from the interior, and the dropping from the trees being found to cause serious damage to the shells I beg to submit the propriety of their being hewn down.
Following Jones’s recommendations, the entire left flank of the Flat Bastion was repaired. The works carried out can be seen in Captain S. Buckle’s photograph of the Flat Bastion from Eliott’s Monument collated by him during the late 1870’s.
Despite these works, on the 15th April 1859, Colonel Lefroy reported that the only armament on the Flat Bastion was four unserviceable 12-pounder and two 12-carronades, which had been there 'since Elliot's time'.19
A J. M . Carter colour print of Prince Edward's Gate from the Alameda dated to 1846 shows three of the four 12-pounders on the west flank of the bastion.
