I have one question because I am not versed in these details, is this the same fort that was found to have a lot of Quaker (fake/log) guns?
No, and no fort had "a lot" of quaker guns.
There are two incidents concerning quaker guns with McClellan.
1. Munson's Hill.
The battery situated on Munson's Hill near Washington had dug six gun positions, but only had 4 guns. They placed quaker guns in the other two positions, and left them behind when McClellan moved against the hill. It is wrongly purported there were no guns on the hill at all, because they left the two fakes behind, and took the 4 real guns with them.
2. Centreville and Fort Johnston.
The original fortification the rebels built was a strong star fort redoubt called "Artillery Hill." They then expanded to 13 redoubts and lunettes, mostly connected by full infantry parapits. From right to left, the works contained, in November '61:
Eastern line
- Cocke's Battery (1 rifle and 3 smaller smoothbores, probably 6 pdrs) - Arty Res
- "some brigade battery to occupy" (Roger's battery)
- Latham's Battery (not stated, probably 4) - Cocke's bde, Longstreet's Division
- (Square work between the Fairfax Turnpike and Braddock Road) Stribling's Bty (2x 12 pdrs and 2x 24 pdr howitzers) - DR Jones' brigade, Longstreet's Division
- (Fort Johnston) Hamilton's Bty (4 rifles) - Arty Res
- Elm. Walton's command (2x 12 pdrs, 2x 24 pdr howitzers and 2x rifles)
- Elm. Walton's command (2 rifles and 2x 12 pdr howitzers)
Reserve works behind Eastern line
- (Artillery Hill) - Elm. Walton's command (4 rifles)
- Dance's Battery (4x smoothbores) - Arty Res
Northern Line
- Brockenborough's Battery (2 rifles and 2 smoothbores) - Elzey's bde, EK Smith's division
- Cutt's Battery (2 rifles and 4 smoothbores) - Arty Res
- Coleman's Battery (1 rifle, 2 howitzers and 1 smoothbore) - Arty Res
- Kirkpatrick's Battery (4 guns) - Arty Res
= 58 guns
The troops occupying the works were Longstreet's and EK Smith's divisions. Van Dorn's division was in reserve. Collectively this force was "1st Corps, Army of the Potomac." The 2nd Corps of two divisions was stationed to the south around Dumfries etc.
Longstreet's Division proper (sans Griffith's bde) had 3x btys, and Rogers' battery was supposed to occupy the work without a battery listed. The Army at Centreville had 9 infantry brigades, each with their own batteries, plus the artillery reserve (9 batteries) and Walton's command (3 batteries, two of the Washington Arty btys were attached to brigades at the time) = 21 batteries, excluding the horse artillery.
Not in the works are:
Arty Res - 3 btys (Woolfolk's, Holman's and Lane's Btys)
All of Van Dorn's divisional arty - 3 btys
Part of EK Smith's divisional arty - 2 btys (Bowyer's and Courtney's Btys)
= 8 additional batteries ready to move into the works = 32? guns
Every single work there was artillery, and there were 8 additional batteries (ca. 32 guns) ready to move into the positions if threatened, and the works were designed to let the reserve guns to rapidly move into them.
The guns weren't enough to fully man all works, and especially those with all-round defence facing to the rear weren't provided with those guns. More guns arrived, delayed by the Potomac Blockade taking guns away.
In December, Beauregard
reported that he the "wooden guns" were stockpiled to replace real ones, and he would only employ them if needed. The idea seems to be that if the guns were to be taken away, they'd be replaced with the quaker guns. For example, if an attack occurred necessitating concentrating the artillery on one side of the position.
The only Quaker guns there are pictures of are those in the rear of Fort Johnston (i.e. facing away from the enemy). Other shots show that the positions facing McClellan were simply empty. It appears they placed the quaker guns in the positions to the rear that weren't in use, and had real guns facing the enemy.
