History
History:
Conrad Emil Lambert Helfrich was born in Semarang, Dutch East Indies, on 11 October 1886, to a Dutch physician father and an Indonesian mother. He was educated at the Royal Naval Institute in Den Helder, where he graduated in 1907 as a torpedo specialist. He saw early service during colonial expeditions such as the 1908 Bali campaign, and in the 1920s became an instructor at the Higher Naval Military School.By the 1930s, Helfrich had become a respected officer in the East Indies. In 1931, he was made chief of staff of Dutch naval forces in the East Indies, later commanding the squadron there, and served as director of the Naval War College. In October 1939, just as Europe entered WWII, he was appointed Commander of all Dutch naval forces in the East Indies. Promoted to vice-admiral in August 1940, he prepared for the coming Pacific struggle.At the outbreak of the Pacific War in December 1941, Helfrich launched an aggressive submarine campaign against Japanese shipping. Dutch submarines under his command sank more enemy ships than the British and U.S. navies combined during those first months. This remarkable success earned him the nickname “Ship-a-day Helfrich” in the American press.In January 1942, the Allied command structure in the region was reorganized into ABDA (American-British-Dutch-Australian) Command. Initially led by U.S. Admiral Thomas C. Hart, Helfrich replaced him as commander of ABDA naval forces in mid-February. Determined to resist, he ordered aggressive attacks on Japanese invasion convoys. However, at the Battle of the Java Sea (27–28 February 1942), the Allied fleet suffered catastrophic losses, including the death of Rear Admiral Karel Doorman. The defeat destroyed much of the Dutch fleet, and ABDA was soon dissolved.Helfrich escaped Java in a Catalina flying boat on 2 March 1942, relocating to Ceylon (Sri Lanka). From there he coordinated the remnants of Dutch naval and air forces in exile. Later, he was appointed Commander-in-Chief of all Dutch forces in the East, combining army, navy, and air command, though the scattered state of Dutch forces made his role largely administrative.
2 September 1945 – Signs Japanese surrender in Tokyo Bay aboard USS Missouri.At the end of the war, Helfrich was promoted to lieutenant-admiral. On 2 September 1945, aboard USS Missouri in Tokyo Bay, he signed the Japanese Instrument of Surrender on behalf of the Netherlands. Returning briefly to Java, he commanded Dutch forces during the politically turbulent early months of the Indonesian National Revolution, opposing compromises with nationalist leaders.From 1945 to 1949, Helfrich served as Commander-in-Chief of the Royal Netherlands Navy, overseeing its postwar reconstruction. He retired in January 1949, later publishing his memoirs in 1950. He died in The Hague on 20 September 1962.

1 April 1942 – One of the most common forms of passive resistance in the occupied Netherlands was the distribution of photographs of Queen Wilhelmina and other members of the Royal Family. These images, often taken from American and British magazines, were reproduced in large quantities and sold for just a few cents. The proceeds were used, among other things, to finance the production of the first illegal newspapers. Shown here: an issue of De Wervelwind featuring Vice Admiral C.E.L. Helfrich.
