“ Callicratides having thus possessed himself of thirty ships, and seeing that the enemy's fleet was now broken, concluded that for the future he was to fight upon land; and therefore sailed straight to the city. Upon which Conon expecting the city would be besieged, made what preparations he could to block up the mouth of the haven. For in that part where it was shallow, he sunk small vessels, laden with stones; where it was deep, he filled great ships of burden with stones, and fixed them with anchors. ”
