Patrick Stanley Vaughan Heenan

A year later, both mother and son moved to Burma with a mining engineer named George Charles Heenan (1855–1912).

The older Heenan is described by some sources as an Irish republican, although he seems to have had a long association with New Zealand, including selection for regional representative cricket teams in the 1880s and 1890s.

There is no conclusive evidence that George Heenan was Patrick's father, or that George and Anne ever married.

However, Patrick was baptised in Burma as a Roman Catholic, with the surname Heenan.

Heenan's mother, Anne Stanley (born 1882), was not married at the time of her son's birth at Reefton, New Zealand.

His birth certificate recorded her maiden name as his surname, and did not include any information about his father.

Patrick Stanley Vaughan Heenan (29 July 1910 – 13 February 1942) was a captain in the British Indian Army who was supposedly convicted of treason, after spying for Japan during the Battle of Malaya of World War II.

Heenan was executed by his wardens while in custody during the Battle of Singapore.

With the defeat of the British imminent, Heenan had mocked the guards, saying he would soon be free, while they would be the prisoners.

In response, British military police shot him and dumped his body into the harbour.

According to Heenan's biographer, Peter Elphick, these events were suppressed by British Commonwealth military censors.

George Heenan died at Pauk, Burma, in 1912.

Patrick's mother then worked as a governess for a family named Carroll.

In 1922, the Carrolls moved to England, and Anne Stanley went with them.

Mrs Carroll died a few years later, and Bernard Carroll, who was an accountant, married Anne.

From 1923 to 1926, Patrick was a boarder at Sevenoaks School in Kent, and in 1927 proceeded to Cheltenham College, as a day boy, in a stream of students preparing for military careers.

Although he was then 16 years old, at Cheltenham he was put in classes with pupils as young as 13.

Accounts of his time at Sevenoaks and Cheltenham show Heenan to have been a poor student and – in the words of the Dictionary of National Biography — a "gloomy, resentful misfit disliked by other pupils".

He nevertheless excelled at sports, especially boxing, due largely to his impressive physique.

According to Elphick, Heenan was unpopular with other students at Cheltenham and was often in trouble with school authorities.

Although he joined the Junior Division, Officers Training Corps (OTC) at Cheltenham, Heenan did not gain any formal qualifications; because of this, he was not able to be admitted to British Army officer training, when he left school at the age of 19.

Heenan instead joined Steel Brothers, a trading company with interests in Asia.

In the early 1930s, Heenan applied for the Army Supplementary Reserve, the only way he could become an officer without formal qualifications.

According to Elphick, had Heenan's illegitimacy been known, it would have prevented him becoming an officer.

He was able to join the reserve by presenting his baptism certificate, along with a certificate signed by his school headmaster, stating that Heenan was capable of performing the duties of an officer.

This was endorsed by the commander of Cheltenham College's OTC.

In 1933, he was commissioned into the Supplementary Reserve.

In 1935, Heenan was transferred to the British Indian Army, with the service number 547/AI.

His parents' address at this time was recorded as Cheam, Surrey, England.

He was put on the Indian Army's Unattached List, and was sent to India.

After six months' training with a British regiment, Heenan was not accepted by any Indian Army regiments.

In 1938–39, Heenan took a six-month "long leave" (an Indian Army tradition) in Japan.

During 1941, as fears of a Japanese invasion of Southeast Asia grew, Heenan's unit was sent to Malaya.

He was transferred to an Indian Army Air Liaison Unit and was sent to Singapore for training.

Following the completion of air liaison training, Heenan was stationed at Alor Setar, in Kedah, northern Malaya, in June 1941.

It was in this area that most of the British Royal Air Force, Royal Australian Air Force and Royal New Zealand Air Force squadrons in Malaya were based.

He had to do an additional six months with another British regiment before being accepted by the 16th Punjab Regiment.

He reportedly performed well in a skirmish on the North-West Frontier, but was later transferred to the Indian Army Service Corps.

According to Elphick, this was a device commonly used to get unsatisfactory officers away from prestigious frontline regiments.

However, Heenan later returned to the 16th Punjabs, but to a different battalion.
