1864 CE to 1875 CE
The Ho begin plundering the lowlands along the Mekong as far upriver as Chiang Khan and as far south as Nakhon Phanom early the following year, directly threatening Siam's security.
The teenage King Rama V (Chulalongkorn) is unable to mount an effective response.
The governor of Khorat takes a force of men across the flooded Mekong at the height of the monsoon and attacks the Ho encamped in the ruins of Vientiane, killing their warlord and forcing the others to retreat to Muang Phuan.
