Xenophon Hellenica 7.5.8

[8] Now I for my part could not say that his campaign proved fortunate; yet of all possible deeds of forethought and daring the man seems to me to have left not one ¹ undone. For, in the first place, I commend his pitching his camp within the wall of Tegea, where he was in greater safety than if he had been encamped outside, and where whatever was being done was more entirely concealed from the enemy. Furthermore, it was easier for him, being in the city, to provide himself with whatever he needed. Since the enemy, on the other hand, was encamped outside, it was possible to see whether they were doing things rightly or were making mistakes. Again, while he believed that he was stronger than his adversaries, he could never be induced to attack them when he saw that they held the advantage in position.
