From D DAY Through German Eyes – Wehrmacht Soldier Accounts of June 6th 1944, by Holger Eckhertz (DTZ History, 2015), Kindle Loc. 1399-1420:
In the afternoon, the English, I recall, insisted for some reason on sending a German-speaking English army priest in among us [German prisoners] to listen to any spiritual concerns we had; this was met with derision. I still recall the face of the army priest, who was very angry at his reception. We heard explosions and detonations from inland and from the beach throughout the day, and naval bombardments from offshore, the shells of which travelled over us with a sound like an express train going past, and always the sound of engines: planes, tanks and trucks, never stopping for a moment.
In the evening, we were taken out of the square and led to the beach. The guards made no attempt to blindfold us or to prevent us seeing the situation. The scale of the operation then became clear to us all, and most of us fell completely silent at what we witnessed.
The sea wall area was being worked on with armoured bulldozers, creating a huge ramp for vehicles to drive up. There were many destroyed vehicles and tanks, some still burning. I saw my bunker, which was collapsed in the frontal part, over the 88mm embrasures; there was smoke drifting from the rubble.
The beach was completely full of transports, including many vehicles we had not seen and we did not even know how to describe: amphibious trucks, tanks with flotation screens, enormous landing craft that were unloading whole columns of jeeps and tanks, directly onto the sand. The English had already cleared a wide lane through the beach obstacles – how they did that so quickly, I have never understood, perhaps with linked explosive charges – and this lane was an absolute highway on the wet sand and out into the sea itself. There were still many bodies, which were lined in large groups on the sand and partly covered with tarpaulins; despite our lack of religion, many of our men crossed themselves as we passed these.
One thing in particular struck many of us as amazing: all along the beach, there were no horses!
This was a surprise for you?
Yes, we found it astonishing. This huge army had brought with it not one single horse or pack-mule! All their transport was mechanised. It may sound bizarre today, but this impressed us greatly, showing that the Allies had no need of horses anymore, as they had such huge oil resources and production capacity. Because, of course, the German armies used horses for transport on quite a large scale right up until the end of the war, due to limited fuel and constraints on mechanised vehicle production. Every German unit had its stables and veterinarian officer, and here were these English without that need at all. For us, this symbolised the Allied capabilities.
