According to the book "Cave Guide to Slovenia, Vol. 1, The Classical Karst Caves" by Ian Bishop (1997), p. 56: "The entrance includes a piece of the history of the cave, the ceiling and walls are heavily blackened as a result of a raid on 23rd April 1941 by members of the sabotage group of the Vojko Brigade who destroyed a petrol dump belonging to the occupying forces." That's all it says. Nothing about explosives or rock being cracked. However I'm sure the rock would have cracked under those circumstances. I have seen surface limestone cracked and broken after a forest fire has passed through in Mexico. A similar account is given in "The Postojna Caves and other Tourist Caves in Slovenia" by Francè Habe (1979), p. 35: "The 1866 entrance partly introduces us to the past history of the caves. A marble plaque has been erected at the beginning of the right-hand wall with the following inscription: "Here, on the 23rd April 1944, the sabotage group of the Vojko Brigade destroyed a petrol dump belonging to the occupying forces."" Again there is no further discussion of the incident. The dates differ, so I suspect one is a typo, but it is likely that it was gasoline rather than explosives that were set off. Mark Minton
