Nashua, NH Fire Alarm received Box 658 for Lake and Vine Streets around 0930hrs. First due units reported heavy smoke on arrival from a large 3sty wdfm mixed occupancy structure. The "Taxpayer" occupied 3 businesses and 17 apartments. Firefighters attempted several aggressive interior attacks during this battle. Command had companies withdraw several times to knock down the heavy overlapping fire from the flat top roof line. Companies were allowed to re-enter the structure around 1230 to finish opening up and finding hidden pockets of fire. The first 6 shots are from my camera phone.
