The battalion trained at Dacca as part of the Eastern Bengal Brigade Area and performed internal security duties for one year.
He was made a Member in Military Division of The Most Excellent Order of the British Empire (MBE) for service as adjutant with 11/12th FFR in the London Gazette 1 July 1941.
With Hitler's attack on Stalingrad it was thought a possible breakthrough to the Middle-Eastern oilfields may occur, so Indian Army units were transferred to Iraq.
Major General Roger Eustace Le Fleming, a British officer, commanded the Waziristan District, from 1944 till June 1948 and was responsible for the long planned withdrawal of regular troops, both Indian and Pakistani, after Independence on 14 August 1947.
He led a small group of volunteers, with mobile artillery transported by mules, shelling the airfield at Poonch from the surrounding hills to the point of rendering it unusable.
For his bravery and successful command of operations, he was recommended by General Sir Douglas Gracey for the equivalent of the British Distinguished Service Order, its 2nd highest gallantry award after the Victoria Cross.
Members of this strong expedition included the Austrians Anderl Heckmair and Matthias Rebitsch, the Englishman George Band and the Genevan Dr. Alfred Tissières.
[14][15] A contemporary film of the expedition is in the public domain[16] In July 1955 Major General Mian Hayaud Din was posted to Washington DC as Chief of the Pakistan Military Mission.
This is the highest decoration that can be bestowed by the US Government upon a foreign military officer and has only been awarded to about 600 persons, including General George Patton; Audie Murphy; Chiang Kai-shek and Dean Rusk.
His Indian Army colleague's wife, Sylvia Matheson, was an archaeologist, who inscribed and gave him a copy of her book Time Off To Dig.
During her time in Sui she later met and befriended Nawab Akbar Khan Bugti, who featured prominently in her next book – Tigers of Baluchistan.
She dedicated this book to General "Gunga" Hayaud Din, as he was known to his closest friends, including Sylvia Matheson and her husband.
Ms. Viqar-un-Nisa Quadri's article "OGDC Memories" published in the Dawn Magazine issue of Sunday, 11 January 1998 attests to his leadership and startup of an organisation in which Russians and Pakistanis worked together successfully, under trying conditions.
On 1 May 1965 he relinquished charge of the OGDC, upon his appointment as Chairman of the National Press Trust (NPT), a position which also included the rank of Cabinet Minister in the Federal Government of Pakistan.
The remains of nearly all the crash victims, including those of Major General Mian Hayaud Din, were buried in a special graveyard at Cairo.
A detachment mainly of artillery was accordingly dispatched in early March to POONCH under the command of a specially selected officer Brigadier (now Major General) Hayauddin.
At the time there was no road to POONCH beyond PANJAR, heavy rainfall had destroyed even the rough hill tracks, a lesser commander would have delayed and hesitated but Major General Hayauddin pushed on with the utmost determination and in spite of immense difficulties successfully coordinated an attack which took place on 17 March 1948.
The determination and skilful action of Major General Hayauddin's detachment constituted a most vital phase in the KASHMIR war.
I entirely endorse all that Major General Loftus Tottenham has written about his actions, and also his recommendation that Major General M Hayauddin is greatly deserving of a Pakistani decoration of the equivalent of a DSO for his great courage, skilful leadership and organisation, dogged determination and invaluable reports – all under conditions which would have dismayed and discouraged a less determined leader."
By the Sovereign's Command Grand Master Grant of the dignity of an Additional Member of the Military Division of the Order of the British Empire to Captain (acting Major) Mian Hayaud Din, I.A.
Major HAYAUD DIN rapidly organised the remaining two companies of his battalion to continue the advance to INYA in an entirely new direction.
The speech of the French Ambassador to the USA Dear General Hayaud Din It is indeed an honour and a great pleasure for me to bestow upon you the Cross of Commandeur de la Légion d'Honneur.
For a long time, France has desired to express to you her gratitude for your brilliant conduct in 1945 – 1946 during the campaign which brought about the surrender of the Japanese forces and Communist elements armed by them in South Vietnam.
At the head of your battalion you established bridgeheads, thus permitting the landing of Allied Forces in the Saigon area; you brought under control difficult regions at the price of heavy casualties; you succeeded everywhere.
By this brave and vigorous action, which put a quick end to a murderous occupation, you spared the lives of numerous of our French Compatriots and of our Vietnamese friends, and, in this way, you gave them liberty sooner.
The presence here today of His Excellency Aziz Ahmed, Ambassador of Pakistan to the United States, emphasises the concurrence of your own Government to this homage rendered to an outstanding officer who has served so magnificently the cause of liberty, the Allied cause, and at the same time the French cause.
Reply by Major General Mian Hayauddin HJ, MBE, MC I consider it a great honour to be awarded the Legion of Honor by the Republic of France.
Karachi – 12 January 1961: At a ceremony this afternoon at the American Embassy Residence Major General Hayaud Din – Director General, Bureau of Mineral Resources and former Chief of Pakistan's Military Mission to the United States, received the Medal of the Legion of Merit, Degree of Officer, from the American Ambassador William M Rountree.
