Before his fatal mission, he wrote letters to his wife Linda and son William Henry which predicted his death: "I am off on a trip from which I don't expect to return but which I hope will shorten the war a bit."
On April 24, 1915, he was ordered to attack a rail junction at Courtrai, Belgium which was vital for the supply of German troops massing after the first gas attack on the Western Front days earlier.
"His slow but stable BE.2c aircraft proved an easy target for the enemy on the ground and a machine gun in the church tower and he was struck in the thigh," Mr Moody said.
"He successfully bombed the target, also damaging his own aircraft in the process as he was so low."
Rhodes-Moorhouse made for home but was hit by more ground fire, in the hand and abdomen.
He managed to land at Merville but refused medical attention until he had made a full report. His aircraft was riddled with 95 bullet and shrapnel holes. He died on April 27, 1915.
British commander Sir John French said the mission involved delivering "the most important bomb dropped in the war so far".
Rhodes-Moorhouse was awarded a posthumous Victoria Cross - the first to be awarded to an airman.
His son William Henry was a fighter pilot during World War II's Battle of Britain. William Henry won the Distinguished Flying Cross before being shot down and killed over Kent on September 6, 1940. He is buried beside his father at the family seat in Beaminster, Dorset.
