Impossible warrior on freedom islands

[Zuvio]

Hello

I got to freedom islands with my warrior. I used horsemen for tank, archers, inquisitors, archimage and priests for buffs/damage. When I got to the islands, i switched out priests for cannoneers, because priests have low damage against non-undead, inquisitors give bless anyway and healing is pointless against large stacks.

Enemies now are a few slightly weaker, some matches but most are stronger and very strong.

My problem is this: with some tactics I can take out an enemy. But of course I lose many units in the process, especially horsemen, since i use target 3. Even with Glots armour, archimage shield, stoneskin 3, source of magic 3 i still lose many horsemen. I also lose some other units, but marginally. I do not have gift, sacrifice or resurrection so i can only use the inquisitors ress one time, which is of course not nearly enough.

Also, I only have 25/51 inquisitors, 14/28 horsemen and 17/23 cannoneers. Without sacrifice, i have no way of increasing these numbers. I have 2 Demons available in Dragon Tooth tavern after doing the Fang quest, but w/o sacrifice i cant use them. I also have 50 Evil Beholders available on the Western Island.

How can I beat Freedom Islands with level 9 on impossible?

I continue to lose units and am unable to replenish them. Am I out of luck due to not finding sacrifice? I have the tactic ready to ressurrect all my units after battle with target, source of magic 3 etc. but i dont have the necessary spells.

If needed, I can upload a savegame of me standing on western island with all items collected and no enemies yet defeated.

I am puzzled how someone like Calinda could beat freedom islands on level 10 with just one run through.

Thanks for your time.
