Thanks for the great post. Of interest, the USN had every intention of seizing both the Cristobol Colon and Infanta Maria as prizes. The Oquendo and Vizcaya suffered catastrophic magazine explosions and were too badly damaged.
The Colon, being a new Garibaldi class armored cruiser, was highly regarded and only lightly damaged in the chase and battle. Her captain scuttled her and ran her aground. Subsequently, she started to slide into deeper water and a USN cruiser attempted to push her back on the beach. Instead she capsized and was lost to further salvage.
The Infanta Maria was more damaged but still in a salvageable sate. Over several months she was actually repaired and made seaworthy for the tow to Norfolk. During the tow a severe storm was encountered and she broke free and grounded in the Bahamas. There she would sink again and not be raised.
Had both been repaired and placed in USN service they probably would have been rearmed with four 8" guns in two turrets and multiple single 6" guns.
All the best,
