bombproof shelter which contained approximately 150 Japanese soldiers. The enemy position was about forty yards forward of the Marine lines. Bonnyman advanced his team to the mouth of the position and killed many of the defenders. His team was forced to withdraw to replenish its supply of ammunition and grenades. Bonnyman again pressed his attack and gained the top of the structure, thereby flushing more than one hundred of its occupants into the open where they were cut down by Marine infantry and a supporting tank. When the Japanese returned fire, Bonnyman stood on the forward edge of the position and killed three of the attackers, but was himself killed as he ordered more charges brought forward. The battle continued for another 10–15 minutes, with all of the Japanese defenders flushed out. Of Bonnyman's original assault party of 21 Marines, 13 had survived. Betio Island was declared secured on the same day. Medal of Honor For his actions during the battle, Bonnyman was posthumously awarded the Medal of Honor. The medal was formally presented to his family by Secretary of the Navy James Forrestal in 1947. His 12-year-old daughter, Frances, accepted the medal on behalf of the Bonnyman family. Remains According to the Defense Missing Personnel Office, Bonnyman's remains were "non-recovered". After the war, the Graves Registration Service recorded his body as having been buried at sea, however this report was later determined to be unfounded. The remains of 36 Marines, including Bonnyman's, were interred in a battlefield cemetery whose location was lost by the end of the war. The cemetery was located in March 2015 by History Flight, Inc., a Florida-based nonprofit that has recovered more than 70 sets of now-identified remains from Betio. Bonnyman's grandson, Clay Bonnyman Evans, a volunteer with History Flight, was present when Lt. Bonnyman's remains were exposed on May 28, 2015, and exhumed on May 29, and recorded the recovery via video and still photographs. Evans' book, Bones of My Grandfather: Reclaiming a Lost Hero of World War II, which recounts his grandfather's life story and the history of the recovery efforts, was published July 10, 2018. On 26 July 2015, the bodies were repatriated to the United States, arriving at Joint Base Pearl Harbor–Hickam in Honolulu Hawaii. On August 27, 2015, his remains were identified and on September 25, 2015, he was returned to his childhood home town of Knoxville, Tennessee. He was
