America entered World War I on April 19, 1917, unprepared to provide the spruce essential to every airplane of the era, which helped protect Allies in muddy European trenches. Airplanes required the spruce found only along 50 miles of Oregon and Washington coastline.
The Industrial Workers of the World (IWW or Wobblies) led a timber strike in the Pacific Northwest that year, demanding management provide fair wages, shorter workdays and safer logging practices.
Although the Wobblies’ strike failed, the Army feared a spruce shortage. The federal government allowed the Army to send soldiers into the woods and establish a government-sponsored union for the timber industry, an unprecedented act to assure uninterrupted spruce production.
Anyone strolling through the Old City Cemetery at Mill Plain and Grand boulevards can see grave markers displaying a portion of a tree with the letters “4L.” The LLLL, or Loyal Legion of Loggers and Lumbermen, the government-backed union.
