As the fear thus inspired had checked all further offensive on the part of the enemy, Quinctius saw that there was nothing left but to invest the place, and after despatching officers to bring up the whole of the naval contingent from Gytheum, he proceeded with his military tribunes to ride round the city and examine its position. [2] Sparta had formerly been unwalled, but in recent years the various tyrants had protected those parts which were level and exposed by a wall; the higher and less accessible positions were defended by permanent military posts instead of fortifications. [3] When the consul had made a thorough inspection of the place he saw that he would have to employ the whole of his force in the attack. Accordingly he completely invested the city with Roman and allied troops, mounted and unmounted; in fact, his entire military and naval strength, amounting to 50,000 men. [4] Some were carrying scaling ladders, others fire, others the different things with which to attack and still more to appal the enemy. Orders were issued for all to raise the battle-shout and rush straight forward to the assault at the same moment so that the Lacedaemonians, threatened on every side, would not know where first to meet the attack or where assistance would be most required. [5] Quinctius formed his main army into three divisions: the first was to deliver the assault in the neighbourhood of the Phoebeum; the second towards the Dictynneum; the third at the place called the Heptagoniae. All these points were unprotected by walls. [6] Though the city was now encompassed on every side by so menacing a foe the tyrant was most energetic in its defence; wherever shouts arose on some sudden onset, when breathless messengers came asking for help, he either hurried to the threatened spot himself or sent others to assist. [7] When, however, demoralisation and panic had set in everywhere, he completely lost his nerve, and was unable either to give the necessary orders or to listen to the messages that came; he not only lost all power of judgment, but was almost beside himself.
