There are also batteries and redoubts facing landward and seaward below this fort; but the other defences have been either razed or dismantled.
That fortress, with modernized permanent works, and a main defence line studded with infantry redoubts farther out and a full interval-organization, had a very considerable perimeter.
Before the rise of the "group" or "Feste" idea - that is, the forts were infantry redoubts for close defense and the fighting artillery was entirely in the intervals.
Unfortunately for the Turks many of the "redoubts" were open at the gorge.
Roads had been built and gun positions prepared, and reservoirs made for water; trenches had been dug and strong redoubts constructed at various important points, though the defensive system was not completely finished when the enemy attacked at Caporetto.
