The reference to Michael's attestation with the Bengal Artillery indicates that he served his first couple of years with the Honourable East India Company. The HEIC maintained a recruiting depot in Liverpool, so I am assuming the attestation occurred in Liverpool.
We don't know Michael's actual movements after making his attestation, but most likely he spent some months training at the East India Company barracks at Warley in Essex. Wikipedia says that "In 1842 the East India Company's barracks at Chatham became inadequate, and they purchased the land [at Little Warley] to move their troops in. Accommodation was created for 785 recruits and 20 sergeants with new buildings for the officers. Married family housing was also provided, and a chapel."
So Mary may have accompanied Michael while he was training at Warley, and stayed in the married quarters. Whether Michael's young bride went with him to India is unknown, but it seems likely that when he went abroad, Mary stayed behind. There don't seem to be any children born of the union in this early period, either in England or India.
