'Against such a power more is needed than an insignificant force of marines; if we mean to do justice to our design, and not to be kept within our lines by the numbers of their cavalry, we must embark a multitude of infantry. For what if the Sicilians in terror combine1
against us, and we make no friends except the Egestaeans who can furnish us With horsemen capable of opposing theirs? To be driven from the island or to send for reinforcements, because we were wanting in forethought at first, would be disgraceful.
We must take a powerful armament with us from home, in the full knowledge that we are going to a distant land, and that the expedition will be2
of a kind very different from any which you have hitherto made among your subjects against some enemy in this part of the world, yourselves the allies of others. Here a friendly country is always near, and you can easily obtain supplies. There3
you will be dependent on a country4
which is entirely strange to you, and whence during the four winter months hardly even a message can be sent hither.
