C-4 Explosive

 

War wouldn't be war without lots of things that go bang, now would it?   That's why we liked C-4.  It was easy to use, and it made noise.  Lots of noise.  C-4 is a plastic explosive.  The pale white foot-long bars come wrapped in olive-drab cellophane.  Each is two inches across and one thick.  It's just like a long bar of soft clay, easy to knead with your fingers.  Even though it is a high explosive, most of the time it is absolutely harmless.  In a pinch we used it to heat "C" rations.  Just tear off an inch-square cube, put it on the ground and light it.  It burned hot and gave off a chemical smell, but it heated the food quickly.  The only rule was to let the stuff burn out completely, and never, never try to stamp it out!

C-4 was versatile.  We often used it to clear booby-traps.  One bar of C-4, a blasting cap, and a length of fuse would destroy anything Charlie could put together.   When we'd find small caches of ammo or mortar rounds, we'd set them off with C-4.

At Patton it came in handy in several situations.  One man was swinging a heavy sledge hammer when the handle broke off right at the head.  We had no tools to extract the remaining piece of wood, so chances of repairing it seemed remote.  After trying everything else, we decided to use C-4.  We stuck a small wad of explosive onto the wood, pushed a blasting cap into it, and set it down with the explosive underneath.  We lit the fuse and stepped back a very respectful distance.  The flame flickered quickly down the length of the fuse.

Wham!  The blast threw the head ten feet into the air in a cloud of dust.  We went over to inspect the damage.  The heavy metal sledge head showed no effects of the explosion, but the wooden plug was gone, disintegrated by the force of the blast.   We inserted a new handle and went back to work.

Road outpost, near Patton II and clogged culvert.

Another time, a culvert down the road from the base clogged, and again we found ourselves without the tools we needed.  But we did have our trusty C-4 and out it came.  We selected a whole bar, inserted the cap, and attached a very long fuse.   We placed the explosive deep within the tangle of brush blocking the metal culvert.   We were still debating whether the water rushing by the culvert would kill the fuse or soak the plastic, when a geyser rose into the air, and a satisfying explosion filled our ears.  Moments later water came rushing through the pipe and the flood waters washing out the road receded.

How powerful was C-4?  Well, from our point of view, it was powerful enough.   Once we rolled a full bar into a pencil-thin string and girdled a tree with it.   We set it off and watched.  The C-4 cut through the foot-thick trunk with ease.

Sometimes we got a little too ambitious with the possibilities of C-4.  C-4 also came packaged in a braided rope.  We speculated that by tying a weight to one end of a C-4 rope, we could toss it into a hedgerow ahead of us.  The explosion would detonate any booby-traps hidden in the brush, saving us the danger of just walking through and finding them.  We had only to wait a day or two for a chance to try it out.

We had moved into a gravel-carpeted clearing, with occasional clumps of dried grass, and low bushes scattered here and there.  A thick hedgerow lay directly in our path.   The line halted, and we waited while the C-4 man moved forward and took the rope from his bag.  Holding the coil in one hand, he swung the weighted end several times back and forth, and then flung the rope into the dense brush.  Satisfied, he fixed a blasting cap to his end, lit the fuse, and trotted back to join the group.  We all crouched down and waited.  In a moment, the rope detonated, and a "Boom!" echoed through the clearing.

An instant later the air was filled with small arms fire.  We dove to the ground and clawed for cover, firing our M-16's into the hedgerow.  The men at the front of the column started back towards us, crawling for their lives.  We had stirred up a hornet's nest.  Rounds ricocheted off the ground, and snapped past our ears.   This stuff was close!

Soon we had a steady fire concentrated on the enemy positions, and the return fire lifted a bit.  The exposed point element now made a dash for safety, leaving us in front.  One by one we each moved back, covering one another.  At one point I passed a shallow pit in the gravel.  Inside was one of the new guys - he'd been with us just three days.  He was crouching, head down, reading his pocket Bible as fast as he could, praying for survival!  We grabbed him and pulled him along with us.

Finally our "strategic withdrawal" was complete, and we were out of range of enemy fire.  We took stock of our situation.  No one had been hit. It seemed a miracle - maybe that praying had done some good after all!  We called in the usual air strike and headed for home.  But it was our first - and last - experiment with C-4 rope to open hedgerows.
