During World War II, Major Airey Neave was head of British Intelligence. He was responsible for providing opportunities for Allied soldiers to escape from occupied territory in Western Europe and therefore he was partly responsible for operations Pegasus 1 and 2. According to Neave, Operation Pegasus 1 was the largest escape from occupied territory during World War II.
In the night of 22nd to 23rd October 1944, a group of 130 troops (aircrew and paratroops) and 8 civilians proceeded to cross the river Rhine. During, as well as after World War II, there was much interest in this successful operation.
This is in contrast to the escape attempt about a month later, under the code name Pegasus 2. This operation failed entirely, for a number of reasons. Only a little above 100 Allied soldiers, who participated in this operation, safely reached the other side of the Rhine. Until a few years ago, there was very little known about this event but it is worthwhile to dig deeper.
