On Aug. 6, 1941, P. Siomes, a German priest, was sitting in his room when the sunny, summer day outside was suddenly lit by an even brighter light that blinded him just before an explosion of sound and heat slammed into the building he was in.
The next month, he gave a full recounting of the hours and days following the bombing in a statement to the U.S. Army.
Author's note: This article is based on a statement from P. Siomes, a German priest who was in the outskirts of Hiroshima when the bomb dropped. His English is great, but not perfect, but we've decided to be as honest to his original text as possible when transcribing. This leaves a few minor grammar and spelling errors, but we do not believe it hinders comprehension. His full statement is available here.
Siomes was part of the Society of Jesus, headquartered in a church at the edge of Hiroshima, and he remembers it being about 8:14 when the city center suddenly filled with a bright, yellow light. He described it as being like the magnesium flash from a camera, but sustained. Over the next ten seconds, he felt an increase in heat, heard what sounded like a small and distant explosion, and was halfway to his door when his window suddenly exploded inward.
He was later glad to have made it away from the window, because he later found that his wall was filled with large shards of glass from the explosion that would've been embedded in him instead of the wall.
Siomes had believed that the damage to the building was from a bomb that burst overhead, assuming that the light was an unconnected phenomenon. But when he went outside to check the damage, all the worst damage was on the side of the building facing the city, and there was no bomb crater in sight.
But looking out into the city, he could see the extent of the damage. Houses were burning closer to town, and nearby woods were already becoming a large inferno. As the men at the facility, mostly monks and priests, begin helping fight the flames, a storm started, and rain began to fall.
Yes, the skies were clear before the bombs dropped, but a sudden rainfall is actually one of the very weird side effects of a nuclear blast. This would help fight the fires, but it also carries tons of irradiated dust, debris, and ash back to earth and helps it cling to the skin of survivors, but Siomes didn't know this in 1945.
He and his fellow Christians began assisting the wounded in addition to fighting the fires. One of the priests "had studied medicine" before he took his vows, and the priests gave as much medical support as they could.
Father Noktor who, before taking holy orders, had studied medicine, ministers to the injured, but our bandages and drugs are soon gone. We must be content with cleansing the wounds. More and more of the injured come to us. The least injured drag the more seriously wounded.
And the damages to the city and surrounding area weren't limited to just the immediate effects of the bomb. High winds damaged infrastructure and knocked over trees and buildings for hours after the initial blast. Siomes believed that this may have been caused by the fires pulling in more air, and research after the war backed him up.
Finally, we reach the entrance of the park. A large proportion of the populace has taken refuge there, but even the trees of the park are on fire in several places. Paths and bridges are blocked by the trunks of fallen trees and are almost impassable. We are told that a high wind, which may have resulted from the heat of the burning city, had uprooted the large trees.
Later on, Siomes would see some of this chaos himself. He went into the city with others to search out some of the missing priests, and they were able to find their quarry. But as they tried to make it back out ahead of the fire, they kept finding wounded trapped under debris, and attempted to rescue them, but then had to move on as the fires got close.
Eventually, they'd take refuge in Asano Park and, as the fires got close:
A very violent whirlwind now begins to uproot large trees, and lifts them high into the air. As it reaches the water, a water spout forms which is approximately 100 meters high.
This infrastructure damage made it harder for survivors to organize themselves and render aid, which was catastrophic as new emergencies kept popping up. Worse, planners had never envisioned losing an entire city in one fell swoop, and they had concentrated key supplies in a few caches near the city center, all destroyed by the bomb and fires.
For Siomes, the priests, and the monks, this all meant that their aid would necessarily be limited. It took more than a day for them simply to find out where all of their own survivors were. Some of them even had the exotic new injuries that only nuclear bombs can create.
One of the priests had been serving in the city when the bomb hit, and while he was processing the sudden burst of light, his hand was already blistering from what would later be identified as radiation. It was the equivalent of an instant, severe sunburn.
Father Kopp is bleeding about the head and neck, and he has a large burn on the right palm. He was standing in front of the nunnery ready to go home. All of a sudden, he became aware of the light, felt the wave of heat and a large blister formed on his hand.
Father Kopp was lucky; he had actually been near the epicenter of the blast but was well protected by the structure which held firm.
As the hours turned into days, the survivors kept tending the wounded and eating what they could find. Bodies lined the rivers and streets, and only skeletons remained of most of the buildings. Survivors had to drag the bodies or carry them on available carts out of the city, gather wood, and then cremate them in the valleys.
Rumors and stories began to rise, especially among the fifty or so refugees that were housed at what remained of the church, about what exactly had happened.
Some were likely propaganda or ill-informed attempts to explain what had happened:
As much as six kilometers from the center of the explosion, all houses were damaged and many collapses and caught fire. Even fifteen kilometers away, windows were broken. It was rumored that the enemy fliers had first spread an explosive and incendiary material over the city and then had created the explosion and ignition.
Some of the rumors were reports of how different victims suffered from the bombs:
Many of the wounded also died because they had been weakened by under-nourishment and consequently the strength to recover. Those who had normal strength and who received good care slowly healed the burns which had been associated with the bomb. There were also cases, however, whose prognosis seemed good who died suddenly. There were also some who had only small external wounds who died within a week or later, after an inflamation of the pharyax and oral cavity had taken place.
A paragraph later, Siomes recalls:
Only several cases are known to me personally where individuals who did not have external burns died later. Father Kleinserge and Father Cisslik, who near the center of the explosion, but who did not suffer burns became quite weak some fourteen days after the explosion.Up to this time small incised wounds had healed normally, but thereafter the wounds which were still unhealed became worse and are to date (in September) still incompletely healed.
But the biggest surprise probably comes at the end of the document where Siomes shares debates between he and his peers about the morality of the bomb.
He doesn't come to a final decision, but he does note:
None of us in those days heard a single outburst against the Americans on the part of the Japanese, nor was there any evidence of a vengeful spirit...We have discussed among ourselves the ethics of the use of the bomb. Some consider it in the same category as poison gas and were against its use on a civil population. Other were of the view that in total war, as carried on in Japan, there was no difference between civilians and soldier and that the bomb itself was an effective force tending to end the bloodshed, warning Japan to surrender and thus avoid total destruction.
It's an argument that continues today, but apparently consumed some of the immediate attention of survivors in the hours and days following its first use.
