[X] Coup de Main. Evade, blow one of them apart, then cripple the other before launching an assault using marine shuttles where you try to seize their ship before they are able to suicide.

[X] Evade. Keep your distance and shoot both of them to pieces. While neither enemy vessel is incompetently handled they have no speed advantage and you are far superior to either.
