Outline of the provenance of this mortar (EL ICARO):
1736?- Cast by Francisco Mir, master founder at Royal Cannon Foundry, Barcelona, Spain
17??- Shipped to Spanish Royal Arsenal of Havana, Cuba (this was the ordnance supply depot which served Florida and probably other parts of the Spanish Empire
approx. 1784-1785- Shipped from Havana to East Florida, Castillo de San Marcos, as part of the armament of the fort.
1790-1821-This bronze mortar is one of only two bronze mortars in East Florida. It appears in numerous inventories of artillery in the fort which remain in the East Florida Papers in the Library of Congress. From about 1790 to about 1812 it was identified as "Mortero de 9 Pulgada" and after about 1812 as "Mortero de 11 Pulgada." The author is unaware of the reason for the change in bore size designation. The other bronze mortar identified in all of the same inventories was one "Mortero de 6 Pulgada" which became "...de 7 Pulgada" at the same time the large one changed nomenclature.
1821-In a few letters between the Spanish and American commissioners, discussinng the transfer of Spanish forts to the US under the treaty of transfer, exactly four bronze weapons were identified among the 23 pieces of artillery to be transferred to the US. These included both mortars mentioned above, plus two "Obus de 7 Pulgada" (7-inch howitzers.)
1821-1838-US ordnance returns recorded in ledgers now in the National Archives listed the two mortars and two howitzers obtained from Spain. The entries in the US documents (various entries within Record Group 156) clearly identified these pieces using nomenclature that varied only occasionally from one return to another. Some returns identified them as "foreign." Most identified the larger mortar as "10 inch" and the smaller one as "6 1/2 inch." After 1838, the fort was heavily armed with large, modern seacoast armament and other US artillery which is shown in returns, but the old Spanish pieces are no longer listed.
1861-Confederate forces in Florida move much of the artillery at Fort Marion (formerly Castillo de San Marcos) to nearby Fernandina. The author has not yet found details, such as listings of individual pieces, but feels safe in assuming the two Spanish mortars were moved to Fernandina. Location of the two bronze howitzers is unknown.
March 3, 1862-Union forces under Samuel F. Dupont take Fernandina, at one point shelling a moving train with Confederate forces onboard. The two mortars are taken as trophies by Navy personnel, and eventually engraved with the details of capture and the erroneous date "February 3, 1862."
1863-1930's-location of the two bronze mortars unknown but one can safely assume they were at some US Navy activity.
1930's-handwritten inventory of trophies in Washington Navy Yard shows two Spanish mortars on display on lawn of one of the admiral's quarters. The weapons are identified as "trophy no. 43" and "trophy no. 44."
1954 (approx.) Washington Navy Yard industrial activities expand, displacing many trophy cannon which are temporarily stored at "Bellvue Magazine" on the Anacostia river in Washington DC, pending receipt of funding for a new museum to house them.
1959-Funding for new museum not appropriated; weapons in Bellvue Magazine largely sold for scrap to local DC scrap dealer. Local antique gun dealer buys "EL ICARO" and offers it in trade to National Park Service.
1960-Details of exchange finalized, dealer receives 6-pounder bronze gun M1841 in exchange for EL ICARO, which is shipped to Castillo de San Marcos for display.
date unknown-Unknown person purchases smaller mortar, bearing identical capture markings, and eventually sells it to Frank Bivins, a Santa Monica CA. luxury home builder and cannon collector (his plastic-bound, limited edition book is entitled "Vari-Type Firearms" and contains a photo of this mortar.)
