circumvaditur civitas a quibusdam vehentibus scalas, aliis componentibus machinas, plerisque obiectu vinearum pluteorumque tectis, iter ad fundamenta parietum quaerentibus subvertenda.
Translation :
and the city was assailed on every side; some brought ladders, others set up engines of war; the greater part, protected by the interposition of penthouses and mantlets, tried to approach the walls and undermine their foundations.
