Order of weapons fire / damage?

[Pablo]

In one game against the religious player I had a fully trained fleet of ~200 dreadnoughts 2 squares from the warp point and my enemy had ~80 talisman baseships 4 squares from the warp point. The plan was to warp (get closer in combat) and get the first shot as a defender fleet. Next turn I lost the entire fleet when the enemy lost ~10 ships. I didn't even look at the movement log as it was obvious that he warped first and got the first shot. Oh well...
