The Fall and Rise of the Indians- an 1857 timeline

[Hindustani Person]

(The Vellore mutiny)
During 1806,in the small town of Vellore, in the south of India, several British Indian soldiers, or sepoys, mutinied against their British overlords because of a perceived attack on their traditions (Hindus were not allowed to wear saffron on their foreheads and Muslims were not allowed to wear beards, among other things.) Although this mutiny was on a large scale, it didn't work out. But what if it did?
In this timeline, the French, hoping to gain some more of India and regain the territories which they had lost in 1803, assisted the Indians with the mutiny, which was led by Fateh Hyder and Muizuddin, the eldest sons of Tipu Sultan ( an important and powerful Sultan who had allied with the French against the British in Mysore, and whose family was kept in Vellore). Fateh Hyder was declared Sultan of Vellore, and gave the French a few more territories such as the Yelagiri hills.His and Muizuddin’s aims was to build an empire in South India, however he was only able to get a few nearby territories before their deaths. Nevertheless, they still sowed the first seeds of rebellion among the Indians.

Sultan Fateh Hyder Sultan Sahib of Vellore (-1815;ruled 1806-1815)

Sultan Muizuddin Mohammad I of Vellore (1774-1818 ; 1815-1818)

Sultan Ghulam Mohammad I of the Deccan (1796-1872; ruled 1818-1872)
Ghulam Mohammad I was kept in Vellore fort as a prisoner, and was to be deported to Calcutta around the same year of the Vellore Mutiny, which was lead by his brother. He was given the throne at the tender age of 22, and was famous for his military achievements.
But that's not the end. As you can see, this isn't only the beginning of this long and epic story. What will become of this? Stay tuned for part 2...

Lord William Henry Cavendish-Bentinck, the Governor of Madras at the time of the Vellore mutiny
The initial British reaction to this was one of anger and fear, the anger that a few soldiers could defeat a mighty power, and the fear that this would make the East India Company lose out on their territories and their hegemony over the subcontinent. The governor of Madras, William Bentinck, was immediately discharged for his role in angering the locals, and whatever change British India could go through was stagnated. Meanwhile, Napoleon, whom had only a year ago defeated Austria and conquered almost all of Western Europe, began to set his sights east. Although his initial jaunts in Egypt and Syria may have failed, with the Vellore mutiny and the establishment of a completely independent state in India, all the way from Vellore up till parts the Northern Circars, the British felt a new threat.
With Bentinck gone, they now had to replace him with William Petrie, who only ruled for a small period of time before his own replacement by the Lord Barlow.
The British however, would not give up and continued to keep troops stationed in south India, with several raids by Vellorean mercenaries not uncommon. This distracted them from the larger problems in Europe and the colonies, and thus, lost battles against the French, who had a lot less to worry about, in both Africa and the Caribbean.
What would the East India Company face next? Would they finally get lucky, or would they die a painful death?
