may use while commanding the battle, as well as an effective force to send against retreating
enemies. Note that cavalry superiority loses its importance in provinces with forests, swamps, and
mountains. Finally, the invader will receive a negative bonus when attacking in a mountain
province, across a river, or when disembarking in a province containing a hostile army unit.
If you win the battle, the enemy will withdraw and you may either move your army to another
province or you may choose to begin a siege or assault against any fortifications in the province
where the army unit is standing.
The defeated party in a battle withdraws from the province, preferably to a province controlled
by its own country or an ally, and which does not contain any hostile army units.
The attacker is always on the left part of the screen, the defender on the
right. The needle points towards the stronger side, weighting in current
strength, technology, morale, leaders and terrain.
Naval Battles
What determines the outcome of a naval battle? Firstly the odds, i.e., the relative difference in
strength between the fleets, are immensely important. Secondly, the difference in naval technology
levels is very important. Thirdly the commander is important, as his skill value in maneuvering,
firing, and boarding will influence the phases of the battle. Fourthly, the outcome of the battle is
influenced by the side that has utilized wind conditions most efficiently, for which your
commander is responsible. You cannot influence this, but note that only one side will get the bonus
for wind conditions. Warships will fight less effectively when there is no wind at all, giving Galleys a
distinct advantage during these conditions. This penalty is decreased as technology is advanced.
If you win the battle, the enemy will retreat and you may either move your fleet to another sea
zone or, if you wish and possess the naval technology for it, begin a naval blockade; or simply
cruise in the sea zone.
The loser of a naval battle must retreat from the sea zone. If the enemy originally tried to force
himself out of a blockaded port, his fleet will retreat to the same port, or else it will retreat to the sea zone
which is closest to one of the country’s own or allied ports, and which does not contain an enemy fleet.
Retreat
Retreat will occur if either of two conditions are present: when your army or fleet is defeated in a
pitched battle or naval battle, or when, during a pitched battle or naval battle, you order your army
or fleet to move away from the province where the battle is taking place, i.e. voluntary retreat.
