What I recommend is that, in addition to knowing how to raise Swadian Knights, you should raise many of them all at once.
Whenever you have the chance of upgrading your Swadian recruits, make them Man-at-Arms so that they become Swadian Knights.
As a result, you will have about 40 to 50 of them.
After that, raise about 40 to 50 Swadian Sharpshooters, because you need a blend of soldiers who can cover the knights and you during battle.
In terms of infantry, it would be great to raise up to 40 Hired Blades. Usually, this combination provides you with great victories. Also, there are hardly any casualties unless you are vastly outnumbered.
