Sergeant Genaust, who was standing almost shoulder-to-shoulder with Rosenthal about three feet away, was shooting motion-picture film during the second flag-raising. His film captures the second event at an almost-identical angle to Rosenthal's shot. Of the six flag-raisers in the picture—Ira Hayes, Harold Schultz (identified in June 2016), Michael Strank, Franklin Sousley, Harold Keller (identified in 2019), and Harlon Block—only Hayes, Keller (Marine corporal Rene Gagnon was incorrectly identified in the Rosenthal flag-raising photo), and Schultz (Navy corpsman John Bradley was incorrectly identified) survived the battle. Strank and Block were killed on March 1, six days after the flag-raising, Strank by a shell, possibly fired from an offshore American destroyer and Block a few hours later by a mortar round. Sousley was shot and killed by a Japanese sniper on March 21, a few days before the island was declared secure.
