IOTL, the First Anglo-Burmese War, in 1824-26, nominally ended in a decisive British victory, giving the British total control of Assam, Manipur, Cachar and Jaintia as well as Arakan Province and Tenasserim, in addition to ending the period of French influence at the Court of 'Ava', and denying the French presence at Rangoon, which had been established by M. Feraud of the French East India Company more than half a century prior, facilitated by the groundwork of Pierre de 'Chevalier' Milard. But this was only achieved at great cost, proving to be the longest and most expensive war in British Indian history. 15,000 British and Indian soldiers died in the conflict (c.72% of these from disease, with this attributed to poor planning and logistics), and the blow to British India's finances amounted to approximately £13M (c. £1.12 billion in today's money- to provide context, this was equivalent to about 1% of the gross GDP of the entire world in 1820, which is estimated to have been roughly US$147 billion).
By 1833, even with the crippling indemnity imposed upon the Burmese after their defeat (of £1M, roughly 28% of Burma's estimated GDP of £3.5M), the war debts incurred by the BEIC in this conflict had precipitated a severe economic crisis in British India, bankrupting the Bengal agency houses. As a result, in the Charter Act of 1833, whilst the British East India Company's charter was extended by another 20yrs, it was forced to give up its remaining privileges, including the monopoly of trade to China (effectively ending the activities of the company as a commercial body, and rendering its activities purely administrative from this point on). And its shareholders voted to approve the Company's nationalisation by Parliament, in exchange for the British government's agreement to assume the debts and obligations of the company, which were to be serviced and paid from tax revenue raised in India, along with the guarantee of annual dividends of 10.5% for forty years (likewise to be funded by taxation revenue in India) prior to a final pay-off to redeem outstanding shares.
But the First Anglo-Burmese War could have easily been a lot more costly, both in lives and expenses, than it was IOTL. In the opening stages of the war, the Lord of Myawaddy and commander of the Burmese forces in the Arakan theater, Mingyi U Sa, had led a column into Bengal, defeating British troops in the Battles of Ramu and Gadawpalin, and capturing Cox's Bazar (hitherto known as 'Palonki'). However, his commander-in-chief, General Maha Bandula, stopped U Sa from proceeding to Chittagong and opening the way to Calcutta, even though it was (presumably unbeknownst to him) only lightly held by the British; and it continued to be largely undefended by the British for several months, with the Barrackpore Mutiny (which had in part been caused by the blow to morale caused by his victory in the Battle of Ramu) also contributing towards this.
So then, let's posit that, ITTL, U Sa's actually allowed to proceed to Chittagong, and captures the largely undefended city (along with its associated territories, consisting of the portion of the present-day Chittagong Division south of the Feni River, excluding the District of Tippera) just as easily as Cox's Bazar. This ramps up the extreme panic in Calcutta, along with the exaggeration of the rumored mystical prowess of the Burmese among the Indian sepoys, lowering their morale still further. And as a result of this, combined with the increased urgency of getting the Bengal Army's troops to Chittagong as quickly as possible, the British officers' increased threats to force their sepoys to take a sea voyage to Chittagong (planning to retake it and Cox's Bazar more quickly by mounting a naval assault, in the same manner as with their invasion of Rangoon), in violation of the Kala pani taboo, causes even greater dissent among their higher-caste majority Hindu regiments. This greatly increases the numbers of the Barrackpore mutineers, to the extent where the British aren't able to suppress the news of TTL's even more brutal 'Barrackpore Massacre' by General Paget; triggering its escalation from a peaceful protest to a full-blown widespread violent armed uprising before the end of the year ITTL, on a scale which wouldn't be seen until 1857 IOTL, with spontaneous revolts subsequently breaking out across British India (and most likely, with Muslim 'Ghazis' also joining in full force, seizing the opportunity to wage Jihad against British rule, as advocated by the Tariqah-al-Muhammadiya movement led by Syed Ahmad Barelvi).
How much of an impact do you think that this POD, with TTL's 'Great Indian Mutiny' preceding that of OTL by 33yrs, and breaking out in the middle of the longest and costliest war in the BEIC's history (which effectively rendered the Company nominally bankrupt even IOTL), having upon the course of history? Would the British East India Company have had any hope of emerging victorious, against the combined hostilities of the mutineers in this 'Great Indian Mutiny of 1824' and those of the Burmese Empire in the First Anglo-Burmese War (and even if so, how much greater would the cost of these conflicts be than the cost of OTL's 1st Anglo-Burmese War)? And with the dominion of the British over India having been far more tenuous, and less deeply entrenched, in 1824-25 than the near-absolute dominance it would have gone on to establish and consolidate by 1857 IOTL, how would you envision things panning from this point- is there a chance that British India itself might not even survive the Mutiny of 1824, or be greatly reduced in its extent in the aftermath of it? In the event of the BEIC's collapse into bankruptcy, and its dissolution, could the British government potentially even decide to cut their losses by abandoning several of the BEIC's territory in India altogether, rather than attempting to impose direct British colonial rule over them? And how different do you envision that the map of India (and the broader region of Greater South Asia) could plausibly look by 1850, 1900, and the present-day ITTL?
