Hey there! Unfortunately, I'm not an expert on the Spanish American War in general. I can point you in the right direction as to where to find the best scholarship though.

Louis Perez Jr. is one of the per-eminent scholars of late 19th century-early 20th century Cuban history. I suggest you check out his book The War of 1898: The United States and Cuba in History and Historiography and mine it and a more general text he wrote, Cuba: Between Reform and Revolution, for sources.
