The great Joao Silva, I have no doubt, will someday recover from his injuries and return to the battlefield, back to work, showing other photojournalists how it's done. But I have many friends Silva has mentored over the years, as his generosity to other photojournalists in what can be a cut-throat profession is legendary. It is very difficult to find a combat photojournalist anywhere in the world who has not been mentored at some point by Silva. It is appropriate, then, for me to link to the work of another New York Times photographer, my friend Bryan Denton, who has been in southern Afghanistan off and on for several years. Click here to see his latest from Arghandab. The work these guys (and gals) do amazes me.
