and protect ships carrying the army to battle. The warships carried up to 30 musketeers, a large number of rowers and a front 6 or 12-pounder cannons or no guns at all.
The Siamese navy was also supported by Chinese immigrants, mostly in
Chantaburi. During the era of
Taksin the Great, his army successfully sieged the old capital of Ayutthaya with the help of the Chinese shipwrights who are masters of building
war junks, which carried more guns than riverine warcrafts.
Vietnamese-Siamese war
The timeline of emergence of a Siamese sea fleet is unknown. Most of its sailors were foreign, such as Cham, Malay, and Chinese. It is assumed that in this era, Ships designs changed from shallow draft Chinese junk (Reu-Sam-Pau/Reụ̄x s̄ảp̣heā) to deeper draft Kam-pan and sloop; with a short period of copied Vietnamese junks. The most prominent naval battle was at
Vàm Nao River.
Franco-Siamese crisis
The
Paknam Incident was a navy engagement fought during the
Franco-Siamese crisis in July 1893. Three French ships violated Siamese territory and warning shots were fired at them by a Siamese fort and a force of gunboats on the Chao Phraya River in
Paknam.
In the ensuing battle, France prevailed and blockaded Bangkok.
Peace was restored on 3 October 1893 after the British put pressure on both the Siamese and French to reach a negotiated settlement.
World War I
The First World War had no direct impact on

Rama VI to strengthen his country's position in the international arena. He also used the war as a means to promote the concept of a Siamese nation.
Siamese sailors were part of a volunteer
expeditionary force, consisting of medical, motor transport, and aviation detachments.
By early-1918, 1,284 men were selected from thousands of volunteers. The force was commanded by Major General Phraya Bhijai Janriddhi and was sent to France.
