Military records for William Tomkins Saull

Hi.

William Tomkins Saull (b1840 - son of John Saull) served in India during, (and survived!) the seige of cawnpore.

Does anyone have any information on his military career, or when he traveled to the US?

I also have a picture of Sarah Saull that could be one of 3 people.

Sarah Adelaide Apperley married W, T. Saull.

Sarah Stone married Vincent Saull.

There was also a daughter of John Saull that was a generation prior... but
I am pretty sure its a shot from when William and Vincent lived in Philadelphia.

Thanks!!!
