This blog has evolved into a review of historical and modern explosive devices, and responses to them. Links are drawn between historical activity and similar activity in the world today. Mostly I focus on what are now called IEDs but I have a loose personal definition of that and wilingly stray into discussions of more traditional munitions, the science and technology behind them, tactical employment and EOD responses. Sometimes it's just about interesting people in one form or another. Comment is welcome and encouraged but I do monitor it and reserve the right to delete inappropriate stuff. Guest posts are always welcome. Avoid any stuff that makes the enemy's job easier for them.

A note on moral perspectives. Throughout this blog there are descriptions of all sorts of people using IEDs, explosives, or suffering the consequences. Some of the people using IEDs are thought of as heroes by some and terrorists by others. One person's good guy fighting for a cause is another person's evil demon.  It's complicated, and history adds another series of filters too. All of us too live in a narrative made up around however we were brought up, what we were taught and what we learned along the way, rightly or wrongly. So if you sense moral ambivalence, one way or the other, well, I'm guilty and I'm not perfect.  By and large though, I have unapologetic sympathy for those dealing with the devices, whether they be soldiers, cops, or whatever, even those who are part of Nazi or other nasty regimes. That's the cool thing about EOD techs - we don't really care who the enemy is.

Russian Partisan EOD search, 1942

I've found an interesting book, "The Partisan's Companion", a guerilla warfare manual produced by Russia in 1942. There's a small section on EOD search for German mines and booby traps which is interesting.

Remember the fascists use mines widely and employ them with cunning and trickery. Quite often they leave various lures in plain sight and conenct them to mines. You should be careful and wary of them.

Do not enter a house which has been left by the Germans until you have inspected the ground around it, The stair steps of the porch, doors, windows, floor boards and various household objects - all of them could be connected to mines.  Any attempt to move them or even a simple touch could produce and explosion.   Use long rope and a grapnel to open the door of such a house.

After entering the house - thoroughly inspect it. First, do a visual inspection, looking for the revealing signs of mines: fresh spots in the wall's plaster, evidence of disturbing the bricks in the walls or stove, fresh scratches on the floor. Also check the electrical wires - see if there are any devices connected to them. If you find suspicious areas- check them more thoroughly.

Try to avoid all kinds of twine, rope and wire in the forest, on the roads and in the houses. They could be linked to mines. Be careful around places which show some disturbance to their uniformity.For example: small lumps of dirt on grass warn you about digging at that site. Be careful not to pick up a rifle or other weapon left behind by the Germans, especially if it is in a highly visible spot. Remember that the Germans sometimes even put mines on the corpses of their soldiers and officers.

The manual then goes on to describe an interesting technique for finding buried clockwork timed mechanisms attached to mines, using a "water stethoscope".  A water bottle is filled almost to within a few centimeters from the top, and a glass tube inserted through the stopper. Put a rubber hose onto the outside of the tube. Then plant the bottle in the ground, with the surface of the water in the bottle level with the ground. Place the end of the hose to your ear and if there is a buried clockwork device nearby you will hear it. 

That sounds like an interesting technique - I'll have to give it a try.
