The role that has been diminished is La Picard de Phelippeaux. He died at Acre while Smith didn't. This in no way diminishes Smith's role, but I would argue it might have been the more vital role because of Phelippeaux's expertise in engineering operations. Unless, of course, that you can show that Smith was also a qualified and educated military engineer which has not been mentioned.

By the way, haven't we already reviewed Smith on the forum in some detail? If so, why are we repeating the procedure?

Finally, though Smith had some good days and bad days, he was not a major player during the period which seems to be overlooked.
