"A laissez-passer (from the French let pass)"
"Historically, laissez-passers were commonly issued during wartime and at other periods, literally acting as a pass to allow travel to specific areas, or out of war zones or countries for various officials, diplomatic agents, other representatives"
Once more from the Ambrose book "Pegasus Bridge":
"Wallwork [Glider pilot of glider # 1 at Pegasus Bridge] and the other pilots were given a special set of orders. These said that the bearer was not responsible to anyone, that he was to be returned to the U.K. by the most expeditious means, and that this order overruled all other orders. " - - Bernard Law Montgomery.
Here from that same era of the Second World War [WW2] and actual example of an American laissez passer. Those men of an Alamo Scout team issued the pass, all and any measures and means as expeditiously granted to the team, extraordinary, accomplishment of the mission of the highest order under direction from the highest authority!!
This was called the Krueger card. A laissez passer issued to the leader of an Alamo Scout team assigned to and under the direct orders of the Sixth Army commander [Krueger].
Those glider pilots having flown and landed safely during the Pegasus bridge operation their further instruction NOT to engage in combat but repatriate to friendly line!
"After unloading their gliders, and after the Commandos had opened a road, the glider pilots were under orders to go down to the beaches and use their special orders from Montgomery to get themselves back to England. In the afternoon [7 June], the pilots had done as ordered"
AT THAT EXACT MOMENT THE COMBAT DANGER TO THOSE PILOTS I WOULD HAVE TO THINK MUCH GREATER THAN THE ACTUAL COMBAT LANDING ON 6 JUNE! EXTREME DANGER NOT ONLY FROM THE GERMAN BUT FROM FRIENDLY FIRE EVEN PERHAPS MORE SO!
I have approved this blog entry! Bernard Law Montgomery, Viscount! Read and obey!
