I know little english.
Usually I use translator.
The problem is a long sentence.
Therefore, I will write a short short.
OP,Belonging to member of the alliance.
OP conquered.
I'm attacked with a part of the troops.
The other part waiting of OP.
After attack , the return.
Alliance leader.
Owner of OP, taken out of the alliance.
Then, this situation has occurred.
I hope that was understandable.
