Did Antony or Octavius take charge of the campaign against their enemies?

Antony and Octavius work together against their enemies.

Antony:

Therefore let our alliance be combined,
Our best friends made, our means stretch’d
And let us presently go sit in council,
How covert matters may be best disclosed,
And open perils surest answered.

Octavius:

Let us do so: for we are at the stake,
And bay’d about with many enemies;
And some that smile have in their hearts, I fear,
Millions of mischiefs.
