Christensen was one of the 76 men who escaped the prison camp on the night of 24–25 March 1944 in the escape now famous as "
the Great Escape". He spoke Danish and some German and was the escape committee’s Intelligence expert on Denmark He teamed up with two Norwegians, Halldor Espelid and Nils Jorgen Fugelsang and the Australian
James Catanach who spoke excellent German and conversational Norwegian, in a group heading for Denmark and possibly ultimately neutral Sweden.
James Catanach and Arnold Christensen reached Berlin as they were seen there by other escapers before changing trains to Hamburg which they also reached successfully only to be caught on the next leg of their rail journey from Hamburg to the naval town of Flensburg on the Danish border. Nearing the border suspicious policemen insisted on carefully examining their papers, checking their briefcases which contained newspapers and escape rations. Close inspection of their clothing revealed they were wearing altered greatcoats. Although the four escapees had split up pretending to be travelling individually hoping to reduce the risk of recapture they were all in the same railway carriage, more policemen arrived and closely examined every passenger, soon arresting all four suspects. The escapees were taken to Flensburg prison. The four airmen were handed over to the Kiel Gestapo and after interrogation were told that they would be taken by road back to prison camp. On 29 March 1944 two or three black sedan cars arrived, Christensen was taken in the second (or possibly a third) car which was flagged down by their senior officer SS-Sturmbannfuhrer Johannes Post who stood beside his own car beside the road in the countryside outside Kiel about 1630 hours. Post had just taken his own prisoner
James Catanach into the field and shot him. Post told his agents to get Christensen, Espelid and Fugelsang out, stating that they should take a break before their long drive. As the airmen walked into the field they almost stumbled over Catanach’s body as they were also shot. Christensen was one of the 50 escapees who had been listed by SS-Gruppenfuhrer
Arthur Nebe, reportedly on Hitler’s personal order, to be killed so was amongst the unfortunate
executed and murdered by the
Gestapo. he was cremated at Kiel. Originally his remains were buried at Sagan, but he is now buried in part of the Poznan Old Garrison Cemetery. His name was amongst the 47 murdered officers named in the British press when the story became public knowledge on or about 20 May 1944 Photographs of Christensen and his headstone are displayed by Auckland War Memorial Museum and another by DigitalNZ. The New Zealand and Australian press maintained a chase for information and justice for their murdered airmen. == Awards ==
