From Wikipedia ref. Oosterbeek:
As of 2003 there were still 138 Allied men with no known grave in the area, and they are commemorated at the
Groesbeek Memorial.
[15] However, evidence of the battle is often discovered even today, and the bodies of Allied servicemen are reinterred at the Airborne Cemetery.
[16] When found, bodies are exhumed and Dutch Graves Registration staff attempt to identify them before they are reburied.
[16] One soldier of the
Border Regiment was discovered and reburied in the cemetery in 2005
[17] and another who had previously been unidentified was reburied in 2006
