This from Chi-Town Fire Photos:

Chicago firefighters were dispatched to a fire in a building @ 18th and Kedzie (1817 S Kedzie). The 14th Battalion landed with a 3-sty vacant, totally involved. Engine 107 deck gunned the rear on their arrival while Engine 109 lead out on side A. Shortly thereafter the 14th boxed it and was taking a defensive posture. In total, multiple hand lines, Tower 5, Squad 1, and a couple point advantages were used to knock down the fire.
