Ptolemy rose, in fact, to a very high command in the Macedonian army, and distinguished himself very greatly in all the celebrated conqueror's subsequent campaigns.

In the Persian invasion, Ptolemy commanded one of the three grand divisions of the army, and he rendered repeatedly the most signal services to the cause of his master.

He was employed on the most distant and dangerous enterprises, and was often intrusted with the management of affairs of the utmost importance.

He was very successful in all his undertakings.

He conquered armies, reduced fortresses, negotiated treaties, and evinced, in a word, the highest degree of military energy and skill.
