Battle of Caleb IV
The Battle of Caleb IV was a successful attack by the Klingon Empire on the Federation outpost at Caleb IV in the 23rd century.

The Klingon force consisted of two divisions, the first commanded by Kor from the   and the second by Kang. As cloaking devices were a new technology at the time, before they departed Qo'noS, Kor spent three days taking the device apart and putting it back together again; this initiative would prove crucial during the battle.

According to Kor, "the battle was over almost before the Federation knew it had begun." He was able to outmaneuver the Federation defenders by attacking with an initial feint, and then returning with his full force, catching the Federation off-guard in the midst of their repair efforts. 

A century later, during a similar attack on a Dominion base at Trelka V, Kor believed that he was back at Caleb IV. ()
