Just below the roadway adjacent to a walking trial.

An upright metal monument with an attached plaque; Pegasus, the symbol of British Airborne units, is atop the monument.

The memorial remembers "Operation Pegasus 1" that occurred here in October 1944.  After Operation Market-Garden, the Airborne-land assault into the Netherlands to get across the Rhine river, several hundred British paratroopers had avoided capture on the opposite side of the Rhine River.  With the help of local resistance and Dutch Freedom Fighters, over 100 soldiers were ferried across the Rhine River at this location with the assistance of the 506th Parachute Infantry Regiment of the 101st Airborne Division.

The text on the plaque is written in Dutch and English.  The English reads:

Operation Pegasus 1
On the night of 22- 23 October 1944, one of the largest mass escapes of WW2 took place.
Over 120 allied soldiers, many of which Airborne troops left behind and 18 civilians involved in the resistance, scattered across the region of Ede managed to cross the Rhine via Renkum.
Here in the floodplains of Randwijk, under cover of the 101St Airborne Division they came ashore in liberated territory.
