The EAS Roanoke was an Omega-class destroyer operated by Earthforce during the start of the Earth Alliance Civil War. Roanoke was one of the ships sent to Babylon 5 to arrest the station's command staff. It was destroyed during the Battle for B5 Independence.
The Roanoke, along with the destroyer EAS Agrippa, two Gunships, and two Hyperion-class heavy cruisers had orders to seize command of Babylon 5, arrest the captain and command staff, and place the station under the direct authority of the President and the Nightwatch. They were aware of the presence of at least the EAS Alexander, which had previously attempted a coup in protest to the martial law declaration of President Clark, and his dissolving of the Earth Senate.
In the battle following Babylon 5's secession from the Earth Alliance, the Agrippa was destroyed by heavy fire; none of the crew made it to the lifepods. 547 personnel died.  The Roanoke was rammed and destroyed by EAS Churchill, which herself was already on fire and heavily damaged. 
In 2261, when Captain Sheridan was captured and tortured on Mars, the destruction of the Roanoke and the loss of her 547 officers and crew were listed on the confession his interrogators tried to get him to sign.
