finding that the
crisis which was approaching was becoming very serious in its character,
took, himself, the whole command within the capital, and began to make
the best arrangements possible under the circumstances of the case to
defend himself there. His numbers were altogether too small to defend
the whole city against the overwhelming force which was advancing to
assail it. He accordingly intrenched his troops in the palaces and in
the citadel, and in such other parts of the city as it seemed
practicable to defend. He barricaded all the streets and avenues leading
to these points, and fortified the gates. Nor did he, while thus doing
all in his power to employ the insufficient means of defense already in
his hands to the best advantage, neglect the proper exertions for
obtaining succor from abroad. He sent off galleys to Syria, to Cyprus,
to Rhodes, and to every other point accessible from Alexandria where
Roman troops might be expected to be found, urging the authorities there
to forward re-enforcements to him with the utmost possible dispatch.

During all this time Cleopatra and Ptolemy remained in the palace with
Caesar, both ostensibly co-operating with him in his councils and
measures for defending the city from Achillas. Cleopatra, of course, was
sincere and in earnest in this co-operation; but Ptolemy's adhesion to
the common cause was very little to be relied upon. Although, situated
as he was, he was compelled to seem to be on Caesar's side, he must have
secretly desired that Achillas should succeed and Caesar's plans be
overthrown. Pothinus was more active, though not less cautious in his
hostility to them. He opened secret communication with Achillas, sending
him information, from time to time, of what took place within the walls,
and of the arrangements made there for the defense of the city against
him, and gave him also directions how to proceed. He was very wary and
sagacious in all these movements, feigning all the time to be on Caesar's
side. He pretended to be very zealously employed in aiding Caesar to
secure more effectually the various points where attacks were to be
expected, and in maturing and completing the arrangements for defense.

But, notwithstanding all his cunning, he was detected in his double
dealing, and his career was suddenly brought to a close, before the
great final conflict came on. There was a barber in Caesar's household,
who, for some cause or other, began to suspect Pothinu
