MILITARY GENERAL WORLD WAR II
Jean Victor de Bruijn (25 November 1913 – 12 February 1979) was a Dutch district officer, soldier, explorer, ethnologist and writer. He spent most of his life in the Dutch East Indies, especially in Dutch New Guinea, working as a colonial administrator and an ethnologist. He gained fame for holding out with native Papuan soldiers in mountainous interior of Western New Guinea against overwhelming Japanese forces, as part of Operation Oaktree, maintaining one of the last Dutch-controlled outposts in the Dutch East Indies during World War II.
Most of the Dutch East Indies were invaded by the Japanese in early 1942, soon followed in April 1942 by Dutch New Guinea, thus isolating the post from the coast.[9] Enarotali still maintained contact with Merauke, the last remaining Dutch stronghold in the Dutch East Indies, and with Australia thanks to liaison seaplanes landing on the Paniai lake. Dutch and Australian governments considered evacuating the post, but De Bruijn was determined to stay there and fight the Japanese as well as gather intelligence, in what would be called Operation Oaktree.[10] In July, he went to Australia to plead his case.[11] It was agreed that he would be sent back to the highlands, with rifles and ammunition, but that no further help could be provided for the time being, since few planes were available.[10] In November 1942, a plane set out from Merauke, bringing him back to Enarotali and the highlands.[12]

When he came back to the highlands, he found out that with the absence of authority caused by his departure, the natives had been convinced by the Japanese to report directly to their headquarters in Fakfak,[13] occupied since April 1942.[9] The following month, in December, the Japanese sent two destroyers along the coast south of Enarotali, landing 450 marines at Timoeka near Kaukenau, and started to construct an airfield and a base.[14] De bruijn raided the local police post at Oeta and disarmed the natives who had sided with the Japanese, then withdrew to the mountains. The Japanese, angered by his raid, sent several reconnaissance planes over the lakes.[15] Owing to the sheer numerical superiority of the Japanese, De Bruijn decided on limiting himself to carrying on intelligence work about Japanese troop movements. In May 1943, he was made aware that a party of 60 Japanese were coming inland.[16] At the end of May 1943, the Japanese, determined to occupy the lake regions in order to deny allied planes from landing on the Lake Paniai and catch De Bruijn, turned up at the lakes, only to realize that Enarotali had been burnt to the ground by de Bruijn and his men during their retreat to safety in the surrounding valleys.[17] While in the valleys, thanks to papuans who had worked for the Japanese, he was able to provide precious information to the Netherlands East Indies Forces Intelligence Service about Japanese forces stationed at Ambon, Seran, Nabire and Timika.[18] De Bruijn kept a low profile, gathering intelligence and using air drops supplies such as ammunition and rifles, training his men on how to shoot with rifle as well as calling airstrikes on Japanese positions at Enarotali.[19] During early 1944, he started reinforcing his band of native papuans with rifles and military training, setting up ambushes against Japanese forces in the region, killing dozens of them.[20] At the same time reports started coming in, saying that more and more Japanese troops were moving toward the mountains, fleeing from their strongholds on the northern coast at Hollandia and Sarmi, which had been invaded by the Americans. They understood that they were facing the risk of getting sandwiched between Japanese troops retreating from the north and the contingent based to the west at Enarotali.[21] In July 1944, De Bruijn decided to evacuate, ending the operations in the highland region.

Over a two year period, this guerrilla force raided and ambushed Japanese positions, pillaged supplies and destroyed ammunition dumps. Even though the highland lakes region was of little strategic value military speaking, it allowed the gathering of precious information on Japanese positions in the region, which would prove useful during the Western New Guinea campaign. Above all, it was essentially a symbolical victory, as de Bruijn was portrayed as the irreducible symbol of Dutch resistance in the Dutch East Indies by allied and dutch propaganda, waving the flag and maintaining the prestige of the Dutch among the inhabitants of the area,[22] just as Hermann Detzner had done in German New Guinea 20 years before, and who was a source of inspiration for De Bruijn.[23] He was personally awarded the Netherlands Cross of Merit, the Netherlands Bronze Cross and the Order of Orange-Nassau by the Queen Wilhelmina.
