Archer: That's Captain.
Archer looks at Mayweather, who gets ready.
Archer: You're relived Admiral.
Mayweather knocks out the Admirals bodyguard. As Admiral Black reaches for his phase pistol. Archer vaporizes him with his phaser.
Later, in the Avenger's Launch Bay, both crews are assembled, as Archer gives a speech from the upper level.
Archer: Our entire Assault fleet, wiped out by a rebel attack. Thousands of your fellow Starfleet Officers dead, if the Defiant hadn't arrived when it did, all of you would be among them. And who is to blame for this? Not the brave men and women who gave their lives for the Empire. The criminals who are losing this war are sitting in their comfortable offices back at Starfleet Command. Their weakness invited our enemies to strike, and their corruption and decadence has brought the empire to the brink of defeat! I've been a soldier all my life, and I will not stand by and let these people destroy and empire that has endured for centuries! I ask you, all of you join me. We can not put down this rebellion so long as our forces are commanded by dishonorable men. Before we can defeat the rebels, we must defeat them! That ship out there... is the key to our victory. With the Defiant on our side, There will be nothing to stop us!
