Originated at the Battle of Velata. In the aftermath, Taufa'ahau slept while Moatunu Vakauta stood guard. Taufa'ahau woke up to find Moatunu still on sentry duty and for the first time bestowed the title Tu'uhetoka on the warrior.

Puakatau Vakauta responded "Tell the Tui Tonga that the same bullet he obtains is the same bullets I'm bringing with my warrior's to Velata, and Let him know that in the dawn of day light we shall see whose bullets is the mightiest"  (they have bullets, we have bullets), Fanga'ihe Si, Loto'aniu and Tongaleleka (Tonga flee in fright), Pangai Lifuka (landing on the marked location), Fetu'ufuka (marked by the star) along with the well-known Tongan phrase Tu'aTalatau Tu'ataKilangi Houmakelikao 'ae Houma Niutao, meaning an individual or insignificant character who picks a fight or task that is far beyond his ability and results in total failure. The phrase originated when Namoa (Tupou) reprimanded Laufilitonga of the Tuʻi Tonga Dynasty for his declaration of war on Taufa'ahau. Laufilitonga was remorseful and submissive as he felt the fierce force and the fury of Puakatau Vakauta and 'Eua. Aftermath
