Hints:

Keep an eye on your melee units; they seem to enjoy standing still, even while they're getting peppered with arrows, until you command them to attack.

Spend more of your money on upgrading, rather than collecting new units. In most scenarios, it's better to have a powerful yet small army than a large but weak one.

Pick up a copy of a good Homer translation and Bulfinch's Mythology to get a sense of how cool this game should have been.

First, start a new war party, selecting what ever
heroes you want and then add all five swordsmen.
