From Sungai Emas to Bukit Meriam, Bujang/Merbok, Pulau Tiga and Kota Kuala Muda one can trace the path of Kedah ancient capitals. Pulau Tiga, near Laguna Merbok was once the location of His Highness Sultan Ahmad Tajuddin's palace and his headquarters after being defeated and drove away by the Siamese in the Battle for Kuala Kedah Fort in the 18th. century. For not so long after, the Siamese attacked the new palace and razed it down. The Sultan escaped to Penang and then Malacca. Kedah was then broken into several administrative territories and ruled by respective Siamese Military Governors. A few years later, after a peace negotiation, the Siamese agreed to re-install His Highness as the Sultan of Kedah with a new throne at the Kuala Muda Fort. The smaller territories were then merged back as Kedah state with the military governors replaced by a Siamese Resident Advisor. The present military camp was a RAF Aerodrome during the WWII and was heavily bombed by the Japanese Airforce on the first day of the invasion of Malaya. The 6th. Brigade (Army) was historically full of military exploits/combats/battles during the Communist Insurgency in the 1970s. There are a large numbers of military cemeteries of Ghurkas' and Commonwealth soldiers. There a number of fallen heroes during the insurgency that came from this command. One was the downing of a Nuri helicopter by the rebels near the Thai border that killed more than a dozen soldiers. The communists had ceased all hostilities since 1989, when a peace treaty with the Malaysian government was signed. The military camp also is the headquarters of the 19th. Royal Malay Regiments with war records such as the famous Black Hawk Downs battle in Mogadishu, Somalia. They helped rescued the surrounded US soldiers with one casualty of their own Regiment members. The present District Police Headquarters was the headquarters/camp of the Police Field Force Battalion during the insurgency. The paramilitary police too has their shares of fallen heroes during the insurgency. The bloody legend of Raja Bersiong (the King with Fangs) whom was believed to be one of the rulers of ancient Kedah was originated from the Lembah Bujang (or Bujangha in Sanskrit = Big Snake = Dragon), one of the 2 valleys (Lembah Muda is the other) that covers half of the Sungai Petani surrounding landscape. The other half is the highland of Gunung Jerai. There are two major rivers Sungai Merbok and Sungai Muda that are suitable for aquasport.
