But during the 1946 Hamburg Trial, there is allegations of British troops using dum-dum bullest which is the violation of international law which Knoechlein claimed under his defense?
I'm interested to know whether there is substantiall evidence that the British used dum-dum bullets against the Germans during the Battle of France
During his defence, Knoechlein claimed that the British soldiers had been dum-dum ammunition and had mis-used a flag of truce. This was robustly denied by the prosecution.
On the 12th day of the trial, 25 October 1948, the Judge-Advocate summed up the trial. He stated that the question of whether British troops had been using illegal ammunition, or mis-using a flag of truce, was irrelevant. If they had, then the British troops had committed an offence under the laws and usages of war. The enemy should then have conducted a proper legal trial. No such trial took place, so if these prisoners were shot out of hand, then this was still a crime.
