Hi,
Daedalus I believe what my alliance mate (death4u) was referring to, was a group of battle reports I forwarded to him a few days ago.
According to the person who sent them to me, it was not one attack that landed 1 second before the cs, but 30 attacks that landed 1-3 seconds before a single cs. Then if I remember correctly, 2,500 Briremes and several thousand defensive ground troops all landed 1-3 seconds behind the cs, in different waves of course.
I can't verify this information because I was not attacked and reports only show down to the minute. But I did see the reports the day of the attack.
If you would like, I can get you in contact with the source of this information, so you can verify for all of us. I could also forward you the reports themselves. They have all recently expired, I don't know if that makes them useless to you or not.
