The older firearm ever discovered in the continental US has been get hold at the site of a slaughter that happen in Arizona in 1541 . Brought to America by the SpanishconquistadorFrancisco Vázquez de Coronado , the bronze cannon was supposed to protect the occupant of the first European settlement in the American Southwest , most of whom were slaughtered before the weapon even had a probability to be lade .

“ Not only is it the first gun ever recoup from the Coronado outing , but interview with experts throughout the continent and in Europe expose that it is also the oldest piece ever found inside the continental USA , ” write the authors of a new study . Though they ca n’t say for sealed , the researchers go on to evoke that the weapon may be the oldest gun anywhere in the Americas .

“ It is also the first known survive model of a artillery of war , an literal piece used in the attempted other conquest of the American Southwest , ” they add .

Launched in 1539 , the Coronado expedition was an ill - fated seeking to get through a fabled cluster of sevengolden citiesthat were rumored to exist in the southwesterly US . The first European incursion into the neighborhood , the mission was force out in 1542 when it transpire that there were no such rich people , follow which Coronado was apparently incapacitate after being kicked in the head by a knight .

Along the way , the conquistador help to found the town of San Geronimo III - also known as Suya - in what is now Arizona . However , the village later gained ill fame as the website of the first successful Native American revolt when member of the Sobaipuri O’odham kindred aggress the townsfolk , killing most of the occupier .

“ Europeans did not regress to what became southerly Arizona for another 150 class , making this the early , most consequential Native American revolt in the continental US , ” write the study authors .

It was at San Geronimo III that the researchers found theancient artillery , know as a hackbut or claw gun for hire . “ This regurgitate bronze cannon is a pristine historical specimen and was found in situ , rest on the floor of a Coronado expedition Spanish structure , ” they write .

“ It is a intention consistent with the mid - to - belated 1400s and was practically disused by the time of the expedition , ” they impart . This observation indicate that the weapon may have been fabricate long before Coronado put off for North America , although all the evidence points to the fact that it was deployed to protect the town of San Geronimo III in 1541 .

However , an examination of the cannon revealed a lack of black pulverization residue in the barrel , indicating that it was never loaded or fired . This chimes well with diachronic accounts distinguish an other morning onslaught by the Sobaipuri O’odham which took the colonist completely by surprise and laid waste matter to the townspeople before any variety of defense could be mount .

“ This final blow seems to be the precipitating event that moderate to the desertion of the wall gun , where it remain snugly encased in an eroded Spanish adobe brick - and - rock - fence complex body part [ ruin ] for 480 age , as radiocarbon and optically stimulated glow dates confirm , ” drop a line the subject area writer .

“ It was depart behind at or bring to San Geronimo to protect an inchoate settlement , which represents the firstEuropean settlementin the American Southwest , and then , also , the first successful Native American uprising in the American Southwest , ” they reason out .
