In this part we find out that I was overconfident. Again...I thought that my main hero was unstoppable. Well it turns out that my enemy also has very powerful heroes and armies. But the bigger problem is sending new troops to my main hero once he takes a foothold in enemy lands. I think that desert makes my heroes very slow so sending reinforcements takes very long time. I tried solving this with a chain of heroes( giving an army to hero who waits at one spot and then goes to next hero and gives him army and so on...). At first this strategy seemed to be working. But it still was a losing battle because I waited so long and my enemy is able to form multiple strong armies by the time I send reinforcements. So next time I will probably have to restart this mission and try something else.
