Nine regiments of Bengal Native Infantry and three of cavalry were stationed in Central India. There was also a large Gwalior Contingent, raised largely from Oudh (or Awadh) and similar in organisation to the irregular units of the Bengal Army, but in the service of the Maharajah Jayajirao Scindia of Gwalior, who remained allied to the British. Almost all these units rose up against their officers during June and July. There were very few British units to oppose them, and Central India fell entirely out of British control.
