In my opinion, that's not the right tactic. Attack with Cyclops?!! In my opinion, they should be sent to the walls as soon as possible to break them down. It is also desirable to speed them up with Shamans. And if morale drops (which happens very often), they will soon be behind the walls, and then the enemy will have a very hard time. And then the rest of the forces will arrive, and that's the end for the enemy...
PS. A small lyrical (read off-topic) digression. When I was playing through the campaign as Orcs, it seemed that they were completely overpowered with their Blood Fury. And many here on the forum think so too. So I was surprised when, in the last mission of the last campaign (as Zehir), I was badly beaten by demons when storming their Castle. That's who is really overpowered – the Demons with their summoning and initiative. And yet, people say that Demons are weak! When they are constantly moving (due to their initiative) and not letting you build up Blood Fury, and at the same time, their numbers are doubled, there is no question of them being weak. And Goblin Shamans don't help, because they can only disrupt magic once, while the enemy hero manages to take two turns before their next move. And Mass Slow and Mass Weakness on Orcs is a death sentence.
In general, I replayed this battle five times, and barely made it (I even thought about quitting the game).
2. When I stormed the Castle with Orcs, everything went well, although negative morale occasionally triggered, but this seems to be due to the peculiarities of the city, which lowered morale, and also the horses with their Aura of Fear. But with Gnomes, I only managed to take the Castle on the third try.
And with the Roar of Terror, something is not quite right. It appeared immediately with Kujin in the mission where she was uniting the Clans. It didn't appear in any other mission. However, in the mission about Alaric, it was in a scroll at the beginning of the game. Similarly, with the Horde Fury for Kujin, it wasn't in the missions, but during the storming of the Demon Castle in Zehir's campaign, it was in a scroll.

Roar of Terror is a powerful ability if the hero is at least level 10, otherwise it may not work. It pushes the creature's turn back a long way, plus it kills initiative, plus it adds Blood Fury points to all warriors.
But it doesn't work on Black Dragons. It seems that combat abilities don't work on them, just like magic. I don't see the logic in this. But what's good about attacking abilities is that even if they don't work on the enemy, Blood Fury points will still be added.

I'm going off-topic too :)
Guys, where did Rylag go? He went from the Lords of the North to the Orcs to gather an army against the Demons, but he didn't appear in the Lords of the Horde.

When completing each mission, put composite artifacts on Kujin, Frida, Wulstren, and Zehir; they will carry them over to the next mission. And put them on as if a big battle is coming, this will greatly help in the last mission, where the heroes (except Zehir) will appear with a standard army to attack the Demon Castles - that is, Zehir completes another task, a cutscene plays, a Demon Castle appears on the map with a powerful army, and one of the heroes appears nearby and attacks the Castle
