Jamming
I saw a documentary about the disastrous assault on Galipoli by British amphib forces...
At one point during the beach landings, many troops ended up falling into the water, and the narrator said that their guns then "jammed" and were useless in the assault after that, which contributed considerably to the problems they faced then. I am unclear on the concept of a jammed weapon. It was my impression that a jam would be a physical obstruction or mechanical failure of some kind, not caused by the mere presence of water. I can see water extinguishing a spark or ignition, but not causing a "jam." - Can/did/does water cause a jam, and if so how? - What would be the effect of water immersion on various weapons since WW l era (Springfields, M-1s, M-14, M-16 etc)? - Do our present military shoulder and sidearm weapons malfunction due to the presence of water? |

Blue,
They only way that I know of that just WATER can be a problem is if the weapon is fired with the barrel full of water. That would be a real problem because the water would act as a serious barrel obstruction. However, weapons that have been dropped into silt, mud, or sand under the water, or into water that has been roiled with mud, sand or silt, such as would happen in an amphibious landing, could definitely jam weapons. As a rule of thumb, the more complicated a weapon is, and the closer the parts fit together, the more it is likely to jam because of foreign material intrusion. All US weapons adopted since about the beginning of the twentieth century have been tested for such conditions before being accepted. The bolt-action Springfield has fewer moving parts and, as far as I know, is not overly sensitive to foreign material intrusion. The Garand and M14 were manufactured with a lot of "room" between moving parts and therefore can handle a lot of stuff in 'em and keep going. The M1911 .45 can deal with dirt pretty well. The M9 Baretta 9mm works in dirt and sand even better than the M1911. I don't have any first-hand experience with the Stoner system (M16) as far as foreign material intrusion. The Israelis bought a bunch of M16s from us back in the 60s and they had a lot to say about the M16s not getting along with desert sand. Their primary shoulder arm at that time was the Galil which is considered by many to function better in a sand environment than the M16. |

Thanks, Rigger...
I think the narrator misspoke himself then... it had to have been the silt or sand that caused the jamming. |

In the days of WWI a gun was a term reserved for a cannon. Some of the larger guns fired a projectile and separate powder charge. If the ammo was wet it wouldn't fire till dry.
stay healthy, Andy |

Water quells fire... so the narrator was using an archaic word for something which was, in fact, probably a mechanical "jam". |
