MINUTES OF PROCEEDINGS OF 
In the left centre where the redoubts command the Florisdorff and Brunn 
road, the distance apart from salient to salient is 500 yards, and some of 
the redoubts are retired so as to lend considerable assistance by their 
flanking fire to those more advanced. 
In the flat ground the redoubts are 1000 yards apart, here there are some¬ 
times employed small intervening open batteries * 
Each redoubt consists of two front, two flank, and two rear faces, the 
gorge being closed by the interior retrenchment. 
A plank bridge across the ditch, and a brick revetted cut in the left rear 
face give entrance to the redoubt, the passage can be closed by a wooden 
door. 
The retrenchment has nine faces, but might practically be called a square 
redoubt with the corners cut off, its parapet is all in earth, it is joined to 
the main work by a loopholed brick wall which sweeps the ditch of the flank 
of the retrenchment. 
This latter is entered through two brick revetted cuts in its flanks, also 
furnished with wooden doors. 
The leading feature of the retrenchment is that its front faces have sunk 
under their terrepleins, galleries, open to the rear in the centre, closed near 
the extremities. 
In one redoubt instead of a retrenchment, there were three mounds of 
earth with covered galleries at their rear, the openings between the mounds 
were closed by traverses placed checker wise. 
The principal points to be noticed in the profile, are that the parapets of 
the exposed faces are 19 ft. thick, those of the retrenchment and protected 
I think it is intended to add more redoubs on small batteries near Leopoldstadt.
