Here are the stats for an attack with non maxed techs. I got impatient waiting for lvl 10 techs and attacked with MT8, IW8, Med8, Compass7, Arch8, HBR6. I did use all 3 buffs (war horn, corsett, penicillin). I attacked from a city directly next to a lvl 10 NPC, 1mi away.

1st wave 2k ballista/110.5k archers (used war ensign for this wave only)
2nd-3rd wave 25k arch/10k war
rest of waves 20k arch/10k war

Time to NPC:
Ballista/archer 7:10
Arch/war 2:56
Transporter/Arch 5:20
Sent 1st wave, waited until 1:56 until it was to reach npc and sent 2nd wave. 3rd wave was sent when 2nd wave was 1:56 away from npc...etc, etc. So my waves were all 1 min apart except for my loot wave which was between my usual 1 min waves (so was an extra wave).

1st wave lost 20k archers and no ballista. Total archer loss was 60k. Total war loss was 40k. Time for capture was around 40 min. Highest attack hero was 144, rest were 113-140.

Although I did not keep track of medals, I know that I got some because I was able to be promoted to General after the attack from Colonel.
