Q1: Does the city def booster raise the stats of towers along with the army?
Q2: How is it possible ?! Force with only 4 k offense to penetrate a city deffense of 13k and kills units deffending??
Hell, Mitko.
Iirc towers only increase their stats when upgraded to the next level but are not subject to the common bonuses that Troops can benefit from. For the second question, it could be that the attack force comprised of Units that the defenders were not well suited to fight against. It could also be that the attackers had a multitude of bonuses increasing their Offense stats.

Hello Dimitri,
Attack force was 4160 pure non boosted of any kind. It was a test raid done with me and my friend. City deffending was boosted with 40% ( 10% city def booster and 30% from amphytheater).As result city deffense was 13 k shown. when 4 k raid landed it killed 1 troyan and one scout.
So how is it possible?
Your City Defense Bonus or better know as CDB gives you a boost in base defense for anyone who's defense is sitting inside your city
so if your CDB is 13k then you get a boost of 130%
good morning friend.
When we are attacked and in the city there is little troop defending always die some of that troop for a tower that defends (provided that the attack is not only 1 swordsman), with the attack that your friend shot you enough to kill you some tower and those 2 soldiers.

It seems like I may have misunderstood the question, Mitko. Did the attacking force still lose the fight or did they win it? It's normal that defenders suffered casualties as well, however, no matter the outcome.
Yes, attack force lost the battle.
Here is how understand the process. (looks like it is not correct acording the results)
attack force with 4100 land over city with 13 000 deffence. it is first substracted : 4160 - 13000 = - 8840
result is bellow O.
All attackers were supposed to die at the walls and passive deffenses before meeting the deffending army.
Yet the test raid (4160) showed that not only they didnt die, but managed to kill 1 troyan (lvl 30) and 1 scout. Even more strange is that few of attacking force survives and returnes back home
only the whole troop dies against Xerxes

I am afraid we cannot provide any more in-depth explanation on the battle calculations than that. You can run more test battles to get an idea if you wish, because that is something we feel players should learn through gameplay.
Totally agree, don't hesitate to share these tests, it's always interesting ! (Unless you want to keep the secret for you ..). 
The battle calculations continue to be a mystery!
Only through tests like this you can make assumptions and come to conclusions!
But high CDB helps for sure when you are defending your city.
That's what I have seen from my personal experience.
