Ranger "Refugees" - [5th campaign, 1st mission]

I just finished playing this mission in 1.5 (I wanted to see the elf with a ballista and chaos magic). And I managed to repel all attacks on the garrisons. As a result, first the red player appeared (as a turn indicator), and on the next turn, we finally captured the first garrison (a human army arrived, with over 10 cavalry units). On the following turn, Briara entered my territory, and the "Hold the Line" objective was completed (although the "repel the garrisons" objective remained incomplete). During this time, I managed to visit all the upgrade locations and defeated Briara in the field, without waiting for her to reach the castle.
