own troops from looting private property, including "furniture, refrigerators, stoves, pianos, clothes[,] [and] even children's toys" due to the breakdown of law and order after the bombing and the ensuing chaos. Many civilian refugees never returned, or did not return for many years, and in the post-war years some land they owned in Darwin had been expropriated by government bodies in their absence, made legal by the Darwin Lands Acquisition Act 1945. The bombing of Darwin resulted in the destruction of 7 of the 11 above ground storage tanks, located on Stokes Hill, in raids on 19 February 16 March and 16 June 1942. This led to the construction of underground oil storage tunnels in Darwin in 1943. Casualties and damage The number of people killed during 19 February raids is disputed. The Lowe Commission, which investigated them in March 1942, estimated 243 victims but, assuming a few were unidentified, concluded "I am satisfied that the number is approximately 250 and I doubt whether any further investigation will result in ascertaining a more precise figure." Some researchers and government officials, including John Bradford (author of In the Highest Traditions – RAN Heroism Darwin 19 February 1942), Dr. Peter Stanley (the Australian War Memorial's Principal Historian and author of several books about Australian military history), Tom Womack (author of The Dutch Naval Air Force against Japan), Paul Rosenzweig (author of Darwin 1942: a reassessment of the first raid casualties), and Rear Admiral Kevin Scarce (governor of South Australia) have said there were 250–262 fatalities. However, a plaque unveiled in Darwin in 2001 gave the total as 292. The plaque indicated 10 sailors had been killed aboard the USS William B. Preston but the US Navy said there were 13 fatalities and Peter Grose, author of An Awkward Truth, said fifteen – he wrote: "With the William B. Preston total corrected to 15, a figure of 297 known dead is the best count anyone is likely to achieve...the full death toll is likely to be a little over 300, perhaps as many as 310 or 320." Lewis and Ingman have revised that to 14 in their 2013 book Carrier Attack. In 2000, Darwin historian Peter Forrest, who spoke to survivors and researched the attacks for an unpublished book, said (as paraphrased by a journalist), "the first Japanese air raids on Darwin probably killed more than double the official figure of 243", but
