This from Eric Haak:
Shortly before 3:00 p.m. on Wednesday (8/3), the Chicago Fire Department was dispatched to the report of a fire at 3110 W. Fillmore. Responding companies reported a large header and a working fire response was then given. Engine 44 landed first and reported a fire in a one-story, commercial garage. The fire building was less than a half mile directly down Fillmore from Engine 107’s quarters. Engines 44 and 109 were the Still Alarm engines and 23 and 95 were on the box. Engine 99 would also have a hydrant as well. Battalion 14 requested a 2-11 shortly after arriving and gave a size-up of 1-story, 100 x 75, communicating to a 2-story ordinary, 25 x 50 with back porches and fire on the second floor. The first picture you see here was taken 20 minutes in. The fire actually turned out to be in two separate vacant commercial buildings in the center with some exposure to Eddie’s Towing which was largely spared. I heard Engines 5, 18, and 26 sent on the 2-11 so I don’t think 107 ever made it in.
