Some very interesting and also OUCH worthy defeats there, any others come on you've all been playing for years surely you've had a FEW major defeats that are noteworthy and memorable
My second worst defeat was this time I was stupid enough to send a 180 dreadnought fleet through a warp point WITHOUT minesweepers well I ran into enough mines to kill about 50 dreads and disable so many of the others that when the bad guy came in with his 200 full health ships he turned my DNs into wreckage.
