QUES: Part of the Russian resistance was credited[by whom?] to the deployment of newly invented blockade mines. Perhaps the most influential contributor to the development of naval mining was a Swede resident in Russia, the inventor and civil engineer Immanuel Nobel (the father of Alfred Nobel). Immanuel Nobel helped the Russian war effort by applying his knowledge of industrial explosives, such as nitroglycerin and gunpowder. One account dates modern naval mining from the Crimean War: "Torpedo mines, if I may use this name given by Fulton to self-acting mines underwater, were among the novelties attempted by the Russians in their defences about Cronstadt and Sevastopol", as one American officer put it in 1860.
