Twelve Green Berets, two tons of explosives...

1. Whoa - that is impressive. And a bit terrifying!

Among my grandfather's photos we found some that appear to have been during his time in the Army Corp of Engineers in World War I. A few of the pictures show the result of explosions - one shows an explosion (540) - and pictures of cards with the amount and type of explosive. Unfortunately, these were loose oversized negatives so I have no way of knowing which card goes with which of the test explosions.

In many of the pictures, the engineers seem to be having some fun but in the one with two men holding what appear to be sticks of dynamite the younger man is not at all happy (549).

Maybe you can give me suggestions as to the various explosions and which card goes with which result? http://www.woodswell.com/family/albums/dmw_photos/1918_World_War_I/index.html I particularly like image 552.
