Why did the colonist depose wingfield, the head of the colony?

According to Wingfield, things really came to a head when he rejected pleas from the Council to provide better provisions for themselves and some of their sick friends.

Attempting to make the colony's stores last as long as possible, the president prudently relied on the beneficence of the Indians, who "did daily relieve us wth corne and fleshe," and after several weeks he was able to muster back to work about twenty men who quickly replenished the colony's supply of rations.

This success was not highly regarded by the Council, however, which by then had "fully plotted" to depose Wingfield.

The councilors had gone so far as to draft "certeyne artycles in wrighting" and to swear oaths to follow through on their plans to rid themselves of the president.
