Hope it helps some of you if for whatever reason you decided to challenge yourself and beat this map on Very Hard difficulty
Played on Speed 90
00:40 Firstly we need to destroy Knights because AI always sends them to rush your offensive at some point
04:05 We need to destroy ALL Archers on the right tower (including those 2 patrolling ones), so enemy will send as many Crossbowmen as possible as reinforcements here, you can see that some Crossbowmen start moving after Archers keep dying
06:00 Send Slaves to bait some Crossbowmen (from the gate) attacks so we can easily focus them first and to bait some traps
06:40 Use those guys to bait another traps, so our Archers won't die stupidly
07:11 Lmao, for some time I didn't notice I've sent melee Camel
07:40 If they're attacking a Gate, they won't shoot at the enemy. You need to give them an order to "Stop" attacking at all first, then select enemy
08:20 And from now on the most interesting part - patience
