[1] From age seven he spent six years in Siam and made close friendships with Mongkut and his heir, Prince Chulalongkorn.

After spending time across Ireland, the United States, and Australia, he returned to Siam where he became an officer before joining the Borneo Company in its teak trade.

He left Siam for the last time in 1914 and spent his last years in the United Kingdom before dying from Spanish Flu in 1919.

[5] In August 1862, Louis arrived with his mother on board the Chao Phaya in Bangkok at age 7 where he would reside in the Royal Palace for the next 6 years.

In July 1863 at age 8, he accompanied Mongkut on his yacht the Royal Sovereign upstream the Chao Phraya river to Ayutthaya.

[3] In early October 1868, while on a vacation with his mother in England at age 11, Mongkut died and was succeeded by his 15-year-old son Chulalongkorn.

She eventually found work in New York City but sent Louis to the United Kingdom to complete his education.

Louis struggled to settle down in Staten island where his family resided, often relying on his mother or her friends for money.

In 1881, Louis moved to Kanni Waikerie along the Murray river northeast of Adelaide, where he worked as a stockhand on Leonard Percival's station.

[2] In 1881, at the age of 25, he returned to Siam and was granted a commission of Captain in the Royal Cavalry by Chulalongkorn, which he served until 1884.

[3] The expedition to Siam's north began on 16 January 1884 where they travelled up the Chao Phraya river, disembarking at Prabat to transfer to another boat which they took up to Saraburi.

Louis then pursued the Haws who began a retreat back to China before giving up and heading arriving in Luang Prabang on 30 May to find that most of his men were sick with malaria, most ended up dying.

They then reached a chief who said that the Haws were unlikely to return to this area and so Louis left the group into the hands of a Siamese officer.

This was due to Hans Niels Andersen arrival back in Bangkok after managing to sell his teak in Liverpool for a large sum.

After a complicated situation, Leckie decided to replace Cheek with Leonowens as the Borneo company agent in Chiang Mai.

[3] As his wife fell pregnant again with their daughter who was born in 1890, Louis built a home for her in Bangkok on land she inherited from her recently dead mother.

He would later warn the local kings of the northern vassal states to not do business with the Bombay Burmah Teak Company (BBTC) due to its involvement in the British takeover of Burma.

In his return to Siam, Louis fell into a state of depression where he often got drunk in Chiang Mai and in the Oriental Hotel in Bangkok.

These comments later led to Leckie travelling to Chiang Mai on 12 August 1895 where he decided to not renew Louis' contract when it ended in 1896.

After the deaths of the king of Lampang and Chiang Mai in March 1896 and November 1897 respectively, the Siamese government began consolidating their authority over the north.

When Shan rebels took over Phrae in a coup on 25 July 1902, they intended to end Siamese control over the area and potentially all of Northern Siam.

With R.C Thompson, Louis erected nine V-shaped teak barriers on major roads in time for reinforcements led by Captain Jensen from Chiang Mai to arrive.

Together with Jensen, Bunwatwongse travelled back to Lampang while Louis continued on to Chiang Mai which he reached on 9 August.

In Chiang Mai, he corresponded with the vice-consul Becket who dispatched Harold Lyle to restore order in Phrae.

During the summer, they travelled to Canada where Louis met his mother and children George and Anna for the first time in 11 years where he gifted them fans from Ayutthaya.

His company dealt with the manufacturing of champagne, whisky, typewriters, cigars, cement and engineering products.

When his son George (age 26) and 2 nephews came over to Britain with the Canadian army for the war, Louis held a party for them.

[3][10] When the Spanish Flu pandemic reached the United Kingdom, Louis fell sick and died on 17 February 1919 at Westcliff aged 62 in the presence of his nephew James Fyssche and friend John Anderson.

This money would contribute Siamese Red Cross, Bangkok Nursing home, and to building Chulalongkorn hospital.

[citation needed] This is due to these stories mostly focusing on Anna Leonowens' time in Siam, which Louis was a boy then.
