Six at the beginning means:
An army must set forth in proper order.
If the order is not good, misfortune threatens.
At the beginning of a military enterprise, order is imperative. A just and valid cause must exist, and the obedience and coordination of the troops must be well organized, otherwise the result is inevitably failure.
