“Secondly. A fortress should command all places round it, and, therefore, all the outworks should be lower than the body of the place.”
“That seems to be quite as necessary as the other.”
“Thirdly. The works furthest from the centre should always be open to those that are near.”
“Everything appears to be thought of in fortification.”
“Fourthly. The defence of every part should always be within the reach of musket-shot, so as to be defended both by ordnance and small fire-arms.”
“It must be a hard matter to take a fortress, when such pains are taken to make it strong.”
“Fifthly. All the defences should be as nearly direct as possible, for experience shows that soldiers are too apt to fire directly before them, whether they do execution or not.”
“What a deal of thought seems necessary!”
“Sixthly. A fortification should be equally strong on all sides, otherwise by being attacked in its weakest point its strength will become useless.”
“That is very plain. A weak part would be sure to be attacked if it were found out.”
