Three hundred forty-three brave firefighters lost their lives while attempting to save others on the never-to-be-forgotten day of September 11, 2001 -- a toll that was unprecedented in the department's history and affected more than 70 companies. In this stunning photographic look at "New York's Bravest," more than 60 photographers have captured images of the stricken firehouses and their makeshift memorial displays, as well as those firefighters who survived the collapse of the World Trade Center. As the city and the nation recover and face the future, the courage and bravery of these incredible heroes will always be remembered.
