How did John Kerry earn his medals?

Three purple hearts, one bronze star, one silver star. What is the story behind each of these medals?

John Kerry Vietnam War Timeline

There is probably a more detailed account in the recently released biography by Douglas Brinkley, Tour of Duty: John Kerry and the Vietnam War, but I didn’t find any excerpts specifically about his medal worthy actions. There are some riveting excerpts here though.

He was involved in many many days of heavy fighting in a short period, but the specific action for which he was awarded the Silver Star is detailed below, exerpts from the Boston Globe.

There are those who say he shot a wounded, escaping man in the back. There are those who say he violated procedure and put his boat and men needlessly at risk. I have no doubt he acted with heroism.

Apologies for the longish snip.
