Why would smith add on to his earlier story?

 The story goes that Smith was kidnapped by the Algonquian chief Wahunsonacock, or Powhatan, for four weeks , during which he survived a form of life or death trial in which , if it is to be believed , his life was saved by Powhatan`s 11- year old daughter , Pocahontas , Smith claimed he was released because of the child`s intervention . After his release he became president of the Jamestown council and was then injured by a gunpowder burn and returned to England . How much truth is in the story I cannot say . 

However , Pocahontas is supposed to have become a regular visitor to the settlement , even bringing them gifts of food to help them survive . In 1613 she in turn was kidnapped by one, Captain Samuel Argall he his said to have held her at ransom , demanding the return of English prisoners and stolen firearms . While Pocahontas was in captivity she was baptized a Christian as `Lady Rebecca` and married a tobacco planter named John Rolfe , in 1616 she came to England and was presented at the court of King James , she died of a fatal illness whilst in England in 1617 aged 22 and is buried in Gravesend Kent . If Pocahontas was a regular visitor to the settlement and was treated well by the settlers , perhaps this might bear out Smith`s story , there must be some reason why she was so well received and married into the community . I think on balance it is highly probable that Smith may well have added to his account , perhaps for personal glory , or possibly because he saw a chance to become leader of the settlement by convincing the others that he had some kind of understanding or rapport with the Indian`s . This of course can only be speculation , the truth is lost in the mist of time

The answer is c. good luck : )
