During the occupation, Friesland, Groningen and Drenthe were on the front line of the air war. Many Allied air routes to Germany were situated over these provinces. Especially during bombings on northern German cities, there was a constant coming and going of hundreds of heavy bombers. Initially, this was only done at night, but from 1943, it also happened during the day.  

For protection, the occupying forces built a formidable defence line. Cities and key military targets were secured by anti-aircraft guns. In Friesland, anti-aircraft guns were located on the Wadden Islands, the coastal strip of Het Bildt, in Harlingen, Lemmer, Franeker and Gaasterland, and in the area around Leeuwarden airfield. 

German observation posts gave directions to the Flieger Abwehr Kanone (Flak) to take Allied aircrafts out of the sky. Radar stations could detect enemy aircrafts as far away as 120 to 150 kilometres. The German radar positions in Friesland were 'Schlei' (Tench) on Schiermonnikoog, 'Tiger' (Tiger) on Terschelling, and 'Eisbär' (Polar Bear) near Sondel in Gaasterland.  

Flak alone, however, proved insufficient to intercept the Allied bombers. During the first two years of the war, night fighter units were stationed at eight Dutch airfields, including Leeuwarden. From here, German pilots shot down hundreds of Allied planes. Most ended up in Friesland, Groningen, northern Drenthe, in the IJsselmeer and in the Wadden region.   

On the night of 14-15 October 1944, a Halifax bomber crashed into the IJsselmeer near Stavoren. Five of the six crew members reached the coast and were received by the resistance in Gaastmeer. Two of them went into hiding in Greonterp. When the Germans threatened to carry out a raid there, the two were hurriedly taken to a rowing boat at night and brought back to Gaastmeer, which is an ideal hiding place because of its poor road accessibility and the abundance of water nearby. On Sunday 15 April, there was a big celebration, Gaastmeer and the surrounding area had been liberated. It was also a celebration for the Canadian and English fliers hiding in Gaastmeer and its surroundings.  

This site is part of the cycling route 'Air War in Friesland' as part of the theme 'Battle for the Wadden'.  

The air war claimed many lives. Some 450 Allied aircrafts and about 150 German fighters are estimated to have crashed in Friesland during the war years. Fallen Allied crew members were usually buried in the nearest cemetery. German casualties were taken to the North Cemetery in Leeuwarden. Surviving Allied pilots were taken into captivity or went into hiding with the help of the resistance. Many pilots remain missing to this day. Some of them were buried as unknowns.  

After the war, the US victims were reburied at the American Military Cemetery in Margraten. The fallen Germans were interred in the German war cemetery in Ysselsteyn near Venray after the liberation. British, New Zealanders, Australians, South Africans and Canadians, along with Poles and Czechs, rest in fifty-seven different cemeteries in the province to this very day. The names of 511 are known; the others have unnamed graves.
