Entry: "Napalm", excerpt:

"Our mechanics also invented an initial version of the napalm bomb. In an additional reservoir filled with a mixture of petrol and sump oil, they showed a fire bomb and an antipersonnel device where the container burst on impact and ignited the liquid. A primitive process, certainly, but one that had considerable impact in terms of physical damage and effect on the morale.
