When I was visiting the La Futa pass German military cemetery in Italy near Florence, I came across this grave. Just the name Louis van Hees and a birth date but no date of death. Would assume this is Dutch or Belgian citizen (traitor) who fought in the German army in Italy in WOII. But cannot find any more information on this guy. Already checked the Belgian, German and Dutch registers. Can someone help?

Staff Sergeant John R. McGrath was born on November 4, 1923, in Eagle Grove, Iowa, to Evert and Mary McGrath. He graduated from high school in 1941 and attended Eagle Grove Junior College for one year before transferring to Coe College.
McGrath ended his college studies when he entered the United States Army on January 27, 1943. He began his basic training at Sheppard Field, Texas, where he qualified for combat crew training. In April 1943, he continued his training as an aerial gunner at the Army Air Forces training base at Laredo, Texas. He then transferred to Keesler Field in Biloxi, Mississippi, where he completed an Army aviation mechanics course specializing in the B-24 Liberator.
After completing his training, McGrath was transferred to an Air Force replacement center, where he was assigned to a combat crew. The crew completed additional training together before being assigned to an operational unit.
McGrath was eventually assigned to the 782nd Bombardment Squadron, 465th Bombardment Group, of the Fifteenth Army Air Force. He served as the nose gunner aboard the B-24 Liberator Old Dutch Cleanser, serial number 42-52575.
The crew departed the United States on April 15, 1944, and arrived at their operational base at Pantanella Air Field in Italy, on May 1, 1944. Old Dutch Cleanser subsequently completed eight bombing missions.
The Mission of June 6, 1944
On June 6, 1944, the mission was to bomb the oil refineries at Ploesti, Romania. Nine B-24s from the 782nd Bombardment Squadron took off at approximately 0800 hours.
During the final approach to the target, Old Dutch Cleanser was struck by enemy flak in its No. 2 engine. The damage caused the engine to catch fire, damaged the fuel-transfer system, and resulted in leaking fuel. Despite the damage, the aircraft was able to continue to the target and release its bomb load.
The formation then began its return flight toward Italy. Two aircraft were lost to enemy flak during the withdrawal.
The crew of Old Dutch Cleansers, aware of the difficulties facing their aircraft, continued toward home. After crossing the Yugoslavian coast, Old Dutch Cleanser began losing airspeed and fell behind the formation. Several B-24s remained with the crippled aircraft in an attempt to provide protection for the crew.
The aircraft continued to lose altitude. In an effort to remain airborne, the crew began throwing equipment and anything else they could spare from the aircraft. Eventually, with the aircraft still descending, the crew prepared for a water landing.
At approximately 1210 hours, Old Dutch Cleanser struck the water approximately 60 miles off the coast. The aircraft remained afloat, allowing members of the crew to escape.
The pilot, copilot, bombardier, radio operator, and a waist gunner were killed in the crash. The surviving crew members inflated their life vests and evacuated the aircraft.
The navigator, engineer, and another waist gunner were able to reach and hold onto a floating aircraft tire. SSgt. McGrath, however, became separated from the other survivors and was alone in the rough sea.
Several B-24s circled the crash site, observing the survivors in the water and noting their position. Sea-rescue aircraft were dispatched to the area.
The navigator, engineer, and waist gunner were ultimately rescued. There was initially no sign of McGrath.
The Account of 2Lt. Leppla
An additional account concerning McGrath’s fate appears in a sworn statement by 2Lt. Leppla. According to Leppla’s statement, McGrath’s remains were brought aboard the rescue aircraft and he was declared deceased.
Leppla further stated that McGrath’s remains were subsequently returned to the water. The rescue aircraft was reportedly taking on water because of the rough sea conditions.
This portion of McGrath’s story should be regarded as an unconfirmed account, rather than established fact. The circumstances described in the statement are difficult to reconcile with the available official record, particularly because of military procedures concerning the handling and recovery of deceased personnel. Further examination of the original sworn statement, rescue records, Missing Air Crew Report, and related military documents would be necessary to establish exactly what occurred.
Regardless of the uncertainty surrounding the final moments of his life, the official record recognizes that SSgt. John R. McGrath was lost at sea and his remains were not recovered and returned for burial.
Memorial
SSgt. John R. McGrath is memorialized on the Tablets of the Missing at Florence American Cemetery in Italy, honoring American service members whose remains were never recovered.
He was posthumously awarded the Purple Heart and the Air Medal for his service and sacrifice

Don't recall those who recommended it, but damn it's good, and heart breaking. I was reluctant to read it because I had already read a book about the Samuel B. Smith. Thanks to those of you who recommended it. You know who you are.
