You are correct, wood rapidly oxidizes, but does not burn. As the wood is heated to its flashpoint and further ont to its burning point, it produces a gas. It is this gas which burns and reduces the wood to ashes. The point where the gas is created is called the interface of the fire and you will will notice if you look very closely that fire does not actually touch an indvidual peice of wood but there is a very small space between the slame and the piece offf wood. This is where the oxidation-reduction chemical reaction takes place which allows the fire to sustain itself at approximately 900 degress farenheit.
