IMO withdrawing Gens at the start is not a good tactic - if the Gen adds morale to the army you lose that and its not very realistic - imagine a General withdrawing at the start of a real fight.

When splitting fleets remember that the slowest ship determines the fleet speed.

I find that winning with the Almos requires some extra work; things that you should do with other factions are critical with the Aloms: focus on developing high valor/high morale troops - making the right buildings and upgrades, combining depleted units correctly, getting some provinces in Spain early to allow you to upgrade weapons, acquiring the right mercs to complement the Almo force mix, and keeping the trade going to pay for it all.

Timing is also important here - wait for the right moment, when the other guy is focused elsewhere.
