In Warlord, at the early stage (even after the emergence of macemen), trebuchet is a very good unit to conquer cities because of it's 100% city attack ability and it's relatively low cost. I often produce as many trebuchet as I can and just produce some defensive units to conquer cities.
There are many merits:
1) it bombards city defence quickly
2) it kills all units with attack below 8 easily. I often kill macemen with no difficulties after City Raider promotion II (best at III)
3) it has a chance to withdraw even failure. So the withdrawn Siege can be reused for next attack.
4) it causes colleteral damage. So, I often sacrifice a few at the beginning and kill the rest of the defending units with no difficulties.
5) it is not costy. Normally, it takes only 1 - 2 turns to be produced from my capital and some production cities.
With this super weapon, I destroyed most of the civs near me in a short period of time. But of course, a strong defensive troop is necessary to protect them, as they are easily killed on the way to the cities.
Hope this sharing gives you another tactics for city conquest
