The Loyal Legion of Loggers and Lumbermen (LLLL), commonly known as the "Four L", was a company union found in the United States during World War I in 1917 by the War Department as a counter to the Industrial Workers of the World.
In October 1917 Colonel Brice P. Disque was dispatched to the Pacific Northwest to investigate the reasons behind what was deemed an inadequate supply of spruce for the Division of Military Aeronautics of the War Department. A career Army officer, Disque had resigned his commission in 1916 to become a prison warden in the state of Michigan before rejoining the Army during the war to work as a "trouble shooter" on military procurement problems.
The summer of 1917 had seen a widespread lumber strike throughout the Pacific Northwest led in part by the radical Industrial Workers of the World. Despite a decision to end the work stoppage in the lumber strike, by September shipments of spruce — a strong and flexible wood urgently needed for the production of military aircraft — had risen only to 2.6 million board feet per month, a fraction of the 10 million board feet required. Col. Disque met with industry leaders in Seattle upon his arrival before setting out on a 10-day tour of lumber operations in the region.
Noting the ongoing labor difficulties in the region, Disque determined to establish a special military division to be dispatched to lumber camps as needed, thereby undercutting any residual difficulties which might be presented by recalcitrant union workers. Disque made efforts to win support for his decision to militarize the timber industry by gathering together a select circle of industry leaders at a meeting held at the Benson Hotel in Portland, Oregon towards the end of the month.
