Mount&Blade/Swadians

The Swadians are a powerful faction, with good crossbowmen and cavalry as well as fairly strong infantry.

The differences between the Swadians and Vaegirs are somewhat aesthetic; while each his its own individual strengths (Vaegir Marksmen fire much faster than Swadian Sharpshooters) there are also some weaknesses that balance this out.

Combat strategies
As one of the two original factions, the Swadians have a more developed troop tree than any faction other than the Vaegirs. Swadians boast accurate crossbowmen and durable knights, but the correct use of a varied party is still the key to victory.

Against infantry
If you are using a less developed party, then it's best to keep your ranged infantry in tight with your regulars until ammo is short. Spreading out and charging is the next logical step. High level cavalry should wait behind sharpshooters until enemies begin returning fire. Spread cavalry and charge to avoid the crossfire.

Although charging them with knights usually works well, the use of ranged units should minimize casualties.

Against cavalry
The Swadians have excellent knights which, when used en masse, have very few weaknesses. Initial charges against cavalry can lose a few men to lances, so it is best to spread out and hang around your ranged units (if you have them)until the enemy breaks their group formation and pursue. Once their advantage is gone, help mop up.

Against archers
Cavalry are the nemesis of archers. Speed is the key, as well as keeping your shield up until you have a shot at an enemy. Spread your knights out and charge early, working your way around the group thinning their numbers until they either fall, or your own foot/ranged men close and finish the job.

Against ranged horsemen
It is a good idea to bring a mix of Crossbowmen and Man-At-Arms/Knights. Swadian horsemen will catch up and often force ranged horsemen to switch into melee weapons. Crossbowmen is also a good choice, since they have ranged. Infantry is a bad choice, since they won't catch up with ranged horsemen. However, if the enemy runs out of arrows (which infantry might survive), they are forced to get up close to the infantry.

Against mixed forces
When faced with an enemy using mixed forces tell all your archers to Hold Position on the highest nearby hill. Next, have your Calvary and Infantry Hold Position behind your Archers. When the enemy is almost towards striking range of your Archers order your Infantry to Charge, wait a second or two, then order your Cavalry to Charge so both forces attack your oppenents at the same time. If your Archers decided it was a smart idea to put away their bows and join the fracas, head a little bit away from the fighting and order them to Hold Position.
