"Mission Accomplished"

I've heard the cover story for a long time now - that the banner that flew behind president Bush on March 1, 2003 when he declared a victory in the war on terror (decide for yourself the veracity of that statement) referred to the sailors on the ship, who had, indeed accomplished their mission and done so capably and admirably, and that the president had nothing to do with it.

However, I am also more than certain that the implied message was what president Bush intended to convey, and as Commander in Chief of the military, he could easily have not had that banner flying behind him.

What I want to know, though, is when did the "official" reason for the banner come out? The earliest reference I can see (with my very limited research - school is keeping me very busy today) is from October of 2003, where the White House insisted that, while they made the banner, the Navy requested it and was responsible for it. When did the story get released, and what was the true intent of the President standing in front of the banner to make that speech? Give me dates and links, not speculation.
