So, too, with regard to spies and intelligencers. Before war commences
your business is to provide yourself with a supply of people friendly
to both states, or maybe merchants (since states are ready to receive
the importer of goods with open arms); sham deserters may be found

were to be announced. Let a spy be ever so faithful, there is always
the risk he may fail to report his intelligence at the critical
moment, since the obstacles which present themselves in war are not to
be counted on the fingers.

undertakes to play this role to good effect.

But to proceed to another topic. The enemy is less likely to get wind

to transmit an order will be very few;[14] while the section-leaders
