Can we draw the following hypothesis from the context?

Context:

David Wooster (March 13, 1711[O.S. March 2, 1710] May 2, 1777) was an American general who served in the French and Indian War and in the American Revolutionary War. He died of wounds sustained during the Battle of Ridgefield, Connecticut. Cities, schools, and public places were named after him. He has been called "a largely forgotten hero of the Revolution."

Hypothesis: David Wooster had not been injured in any war prior to the Battle of Ridgefield
It's impossible to say
