on the contrary, when Agis learned that Agesilaüs had plotted to make away with Leonidas as he was trying to withdraw to Tegea, and had sent men to assault him on the road, he sent out another company of trusted followers who took Leonidas under their protection and brought him safely to Tegea.
Thus the enterprise of the kings was making good progress and no one tried to oppose or hinder them, when one man, Agesilaüs, upset and ruined everything. He allowed a most shameful disease of avarice to wreck a most noble and most truly Spartan plan.
For since he was an exceedingly large owner of valuable land, but owed huge sums of money, being unable to pay his debts and unwilling to give up his lands, he persuaded Agis that if both his projects should be carried through at the same time the resulting convulsion in the state would be great; but that if the men of property should first be won over by a remission of their debts, they would afterwards accept the distribution of land contentedly and quietly.
