Artillery question

[TomP]

If a major war had broken out requiring full National Guard mobilization in 1900 then the deployed forces would still have had Civil War era bronze smoothbore artillery...

Good point. All of the artillery on display at NPS Civil War sites came from arsenals in Northern states where they had been stored for several decades. They were nearly all obsolete and were distributed to the National Military Parks starting in 1900.

The field artillery for the U.S. Army in the years approaching 1900 was primarily the trusty wrought-iron 3" ordnance rifles and the newer 3.2" steel breech loading rifles.

The Spanish-American war was a major war that had just happened. I suppose those 3" ordnance and 3.2" breech loaders went into the land engagements.
