Attack on Sydney Harbour [SEP] USS "Chicago"s survival
Several factors beyond the control of any of the combatants contributed to the survival of USS "Chicago". At the time of "M-24"s attack on "Chicago", the latter had spent some time preparing to depart from Sydney Harbour, and although still moored and stationary, was producing large volumes of white smoke as the boilers warmed up. This smoke, streaming aft under the influence of the wind, and contrasting against the dark, low-lying cloud, may have given the impression that "Chicago" was moving, causing "M-24" to lead the target when firing its torpedoes, and consequently sending its torpedoes across the bow. Another factor that may have influenced "Chicago"s survival was the extinguishing of Garden Island's floodlights minutes before "M-24" fired its first torpedo, impeding targeting.
