Andy,
Thanks for that great article. As you said, these howitzers were transported on horse back which allowed them to engage the enemy in places heavy guns could not:
“The heavy horse-drawn guns could not always be transported to the positions where they were in demand, further, the heavier guns had greater range than was actually needed in close wilderness fighting.”
I also found this passage about Daniel King very interesting:
“…on the ratification of the Constitution, King entered a float in the parade held in Philadelphia on July 4, 1788, in celebration of the event. On his float was built a small furnace which was in full blast throughout the procession, during which time Mr. King finished a 3-inch howitzer. At the end of the parade he mounted this gun and fired it along with the other artillery pieces on Union Green.”
