In the 2250s, the Chech'Iw was under the command of General Gorkon, with Mazhtog as his first officer. During Gorkon's command, the Chech'Iw clashed sixteen times with Federation forces, five of those with the Starfleet starship, USS Dauntless under the command of Captain Diego Reyes. In an engagement with the Dauntless at Xarant in late 2258 or early-2259, the Chech'Iw severely damaged the Pyotr Velikiy-class ship, killing 18 of its crew, including the first officer, Commander Rajiv Mehta.
