"There's only one reason why someone would put the horses in the swamp.. ...they didn't want anyone to find them."
{There are three "categories" of the CHEMICAL soil-conditions which affect long-buried iron relics:
High-ground (well-drained soil, such as a hillside)
Non-saltwater lowground soil (such as a swamp, or even a low creekbank)
Saltwater low-ground soil (such as a coastal saltmarsh).
Each of those three soil-chemistry environments have a significantly DIFFERENT AFFECT on the relic's iron ...which must be carefully considered when we attempt to preserve the relic by using either Electrolysis or Zinc-&-Lye Bath to remove the rust/soil concretion from the relic. Iron (unlike brass, copper, silver, lead, etc) is a very porous metal. The thousands of microscopic pores can permit salts and acids to penetrate past the iron's "skin," sometimes - but not always - deeply within the relic.
If saltwater is given decades to penetrate the iron, when the relic is excavated and it dries out, the salt gradually forms crystals which can literally crack the relic's skin into fragments.
Swampwater (or any "stagnant" surface groundwater) contains tannic acid - from decaying leaves. In such water the tannic acid is very weak ...but given decades, it can cause serious "leaching" of iron molecules from out of the "skin" of the iron relic. What is left behind in that relic's skin is the carbon (specifically, the mineral known as Graphite) that was in the original iron ore. This is why we artillery-shell collectors tend to call a swamp-dug shell a "graphitized" shell. The skin of such shells
resembles pencil-lead (which is actually Graphite). It can be quite soft.}

Booth's
bay mare was wearing a single bit like this half cheek snaffle. Relatively inexpensive bit for the horse-in training and perfect for a horse that was continuosly
breaking it's reins.
