Battle of Suoi Chau Pha
The Battle of Suoi Chau Pha (6 August 1967) was fought during the Vietnam War between Australian troops and the Viet Cong. The battle took place during Operation Ballarat, an Australian search and destroy operation in the eastern Hat Dich area, north-west of Nui Dat in Phuoc Tuy province. Following a covert insertion the day before which had caught a number of Viet Cong sentries by surprise, A Company, 7th Battalion, Royal Australian Regiment (7 RAR) had patrolled forward unaware of the presence of a large Viet Cong main force unit nearby. Clashing with a reinforced company from the Viet Cong 3rd Battalion, 274th Regiment, a classic encounter battle ensued between two forces of roughly equal size. Fought at close quarters in dense jungle amid a heavy monsoon rain, both sides suffered heavy casualties as neither was able to gain an advantage. Finally, after a battle lasting several hours, the Australian artillery proved decisive and the Viet Cong were forced to withdraw, dragging many of their dead from the battlefield after having suffered crippling losses.
Nguyễn Phúc Chu
Together they defeated a Nguyễn military force in 1695. The new Champ king, Po Saktiray Da Patih (younger brother of Po Sot), made a treaty with Nguyễn Phúc Chu. The result was the Cham rulers in Panduranga were recognised as "Trấn Vương" (local lords) for the next 135 years, though they had no authority over Vietnamese living in the area. In 1714, Nguyễn Phúc Chu sent an army into Cambodia to support Keo Fa who claimed the throne against Prea Srey Thomea (see also the article on the Dark ages of Cambodia). The army of Siam also got involved in the war, the Siamese sided with the Prea Srey Thomea against the Vietnamese (this was during the time of the Ayutthaya Kings of Siam). The Vietnamese won several battles against the Siamese (including the battle of Banteay Meas) but shifting fortunes led to the war ending with negotiations rather than military defeat on either side.
