Captain Gustave M. Heiss
Pilot B-25C 41-12442 Missing In Action (MIA) September 4, 1942

Background
Gustave Marinius Heiss was born April 25, 1913 to parents Gustave Marinius Heiss, Sr. and Bonnie R. (née Barber) Heiss in Meridian, Mississippi. At a young age, the family moved to Houston, Texas. He attended two years of college.

Wartime History
On August 12, 1939 Heiss enlisted in the U.S. Army for the Philippine Department with serial number 06298650. He became an aviation cadet, earned his wings and was commissioned as a 2nd Lieutenant with serial number O-392820. Assigned to the 5th Air Force, 3rd Bombardment Group (3rd BG), 13th Bombardment Squadron (13th BS) as a B-25 Mitchell pilot.


Royce Mission
On April 11, 1942 took off piloting B-25C 41-12442 as one of nine B-25C Mitchells each with a bomb bay fuel tan for extended range plus three B-17E Flying Fortresses staged from Batchelor Field near Darwin for the 1,500 mile flight northward to Del Monte Airfield on Mindanao. On April 12, 1942 and April 13, 1942 this B-25 participated in the Royce Mission flying bombing missions against Cebu and Davao. No American aircraft or personnel were lost. Afterwards, the bombers helped evacuated a number of important military and diplomatic personnel at Del Monte Airfield back to Darwin. For his role in the Royce Mission, Heiss earned the Silver Star and was promoted to the rank of Captain.

Gus Breymann (nephew of Gustave Heiss) adds:
"I've talked to others who participated in the three-day raid on the Philippines, and they all said that their mission would have been famous were it not for the fact that it occurred at exactly the same time as Doolittle Raid led by Jimmy Doolittle over Tokyo. Doolittle, of course, deserved a great deal of press coverage, but it overshadowed the Royce Mission. Still, the Royce raid did make the front page of the "New York Times" in the middle of April 1942."

Afterwards, Heiss was based at Charters Towers Airfield in Queensland in Australia and 7 Mile Drome (Jackson) near Port Moresby in New Guinea.

Mission History
On September 4, 1942 took off from 7 Mile Drome (Jackson) piloting B-25C "The Queen" 41-12472 on a bombing mission against Japanese warships in Milne Bay but found nothing. Returning in darkness, the formation was flying at roughly 3,000' when bad weather closed in. This B-25 was observed to turn on its landing lights and made several erratic turns before diving into the sea off the southern coast of New Guinea. On impact, it burst into flames before submerging quickly between Hood Point and Keppel Point approximately six miles offshore. The entire crew was officially listed as Missing In Action (MIA) and earned the Purple Heart, posthumously.

Memorials
Heiss was officially declared dead the day of the mission. He earned the Silver Star with Oak Leaf Cluster and Purple Heart, posthumously. Heiss is memorialized at Manila American Cemetery on the tablets of the missing. He also has a memorial marker at Rose Hill Cemetery in Meridian, MS.

Relatives
Gus Breymann (nephew of Gustave Heiss)
"My uncle's home town was Houston, Texas, but he was born in Meridian, Mississippi. That's why you see the Rosehill Cemetery marker in Meridian. His marker is placed next the graves of his mother and father."
