Starfleet Klingon-Romulan border blockade

The Starfleet Klingon-Romulan Border Blockade was a Starfleet blockade during the Klingon Civil War, made up of 24 starships. It's objective was to expose the Romulan aid to the House of Duras, and to prevent the Romulan ship to cross the border. A method was devised by Lt. Commander Geordi La Forge to use a tachyon detection grid to detect any cloaked Romulan ships attempting to cross the border.

A fleet of four Romulan starships gathered at the border, led by Subcommander Sela. Unable to cross without being detected, Sela attempted to disrupt the grid by bombarding the USS Sutherland with tachyons, creating a blind spot. Captain Jean Luc Picard ordered the fleet to rendeavous at Gamma Eridon. However, temporarily in command of the Sutherland, Lieutenant Commander Data recognized her tactic and used the residual tachyons to detect the ships trying to pass through, exposing the Romulan connection and tilting the balance of the war to Gowron.
