Many years ago, I befriended a couple of Germans who had served in their forces during WWII. One of them had been severely wounded and incapacitated early in the war, and had subsequently been appointed as Commandant of a POW camp in Germany.
Over the years, amongst other things, we discussed the mechanics and policies of prisoner incarceration in Germany. What he told me directly challenges many of the comments made here, and in The Code.
On a straight numerical basis, the holding of prisoners was not considered to be any impediment to the German war effort. Depending on the particular installation, they had one guard for every 30 or so prisoners. They considered that having taken 30 of their opposition out of the fight, in exchange for one of theirs was a pretty good bargain.
In addition, as the war progressed, many of the German guards were soldiers who had been injured at the front, and were considered unfit to return to front line service. However, guard duty at a POW camp was considered light duty, and they were quite fit for that. So, provision of guards for POW’s did not have any particular negative effect on the German war effort.
Similarly, the Germans did not consider prisoner escapes to be any big deal. The standing orders for an escape were that a small group of guards would conduct a search over a specified search area for a 24 hour period, then return to barracks.
After that, the responsibility for capturing escapees fell to the local civil authorities as a part of their normal policing duties. They considered escaped prisoners as no threat, since they would be focused on survival and escape, as opposed to doing any kind of damage. Most escapees were recaptured after they succumbed to exhaustion and despair and surrendered.
There were a couple of occasions in which some prisoners escaped into an area where an active German unit was camped while on R&R. On those occasions the unit took the opportunity to launch a search operation; however this was used as a training operation for the unit in question. Hunting escaped prisoners was considered good training for hunting partisans on the Russian front. So, on these occasions, the training gained was of benefit to the German war effort, not an impediment.
There were no forces specifically allocated for prisoner search and capture. So, given all this, escaping prisoners had no noticeable effect on the German war effort.
With regard to escape planning: he said that most of the time the Germans knew of POW escape plans. As a matter of policy they allowed them to proceed, to a certain point, at which point they were stopped.
The Germans considered boredom to be a very dangerous issue in POW camps; if the prisoners became bored, they would become uncontrollable. Boredom could quickly turn ugly. So the Germans considered POW escape planning a very vital part of POW recreational activity; so long as they were planning escapes, they were busy and not bored.
Boredom was also a major problem with the guards; so they were encouraged to uncover the escape plans, and discreetly monitor them as they progressed. This gave them something to keep their minds occupied, and in thwarting the plans, made them feel that they were still contributing to the German war effort.
So both the planning and the execution of escapes served the needs of both sides of the wire.
According to the Germans, the biggest downside of holding POW’s was the issue of feeding, housing, clothing and generally maintaining them. This was in addition to the logistics of actually distributing the supplies. As the war progressed food, supplies, fuel and transport became short; these resources had to be diverted from the front to the POW camps.
This diversion of resources did effect their men at the front and did impede their war effort. So, ironically, it would have been to the German’s benefit if more prisoners had escaped.
