Naval Base Hollandia

The Battle of Hollandia started on April 22, 1944, as part of the New Guinea campaign. [3] United States Armed Forces as part of Operation Persecution landed at both Humboldt Bay and Tanahmerah Bay, 12 miles west of Humboldt Bay. Both bays are in a rain Tropical rainforest climate. On May 9, the Seabee 113th Construction Battalion arrived at Humboldt Bay and start construction on the port and docking facilities. Buildings and roads were built at the port base camp. A power station, water purification, Seabee camp and depot were built. To receive all the needed supplies for the new Naval Base a pier for Merchant Navy ships was built and completed on June 9. To prepare for the staging of troops, a second pier was built, starting September 13 and completed on November 23. A destroyer repair base was completed on September 1. Seabee 102rd Construction Battalion arrived at Humboldt Bay on June 12, 1944, to speed up construction projects. To expand the base a major land fill project was done into the bay. Beach landing ramps were built to support the loading and unloading of LST ships. Before the piers were completed the Seabee installed pontoon barge docks. Seabees were sent 25 miles west to Tanahmerah Bay on June 19.[4] At Tanahmerah Bay a large fuel oil and diesel tank farm was built. From Tanahmerah Bay some Seabees were sent 8 miles inland to Lake Sentani and built an advance naval headquarters. Seabee 119th and 122nd Construction Battalion arrived to help with work at Tanahmerah Bay. The 122nd Battalion worked at facilities the Wakde Airfield on an Island west of Humboldt Bay and at Aitape east of Humboldt Bay. Naval Base Hollandia supplied most of the supplies for the invasion of the Philippines. Some of the base was moved to more forward bases by the Naval Construction Maintenance Unit 558. The Naval Base Hollandia was closed in December 1945 and the facilities were sold to the Netherlands East Indies Government. .[5] [1][6]
