As for the exact date of Cap's disappearance, I think it is in February 1945. There was an auction for the props from the movie a while ago, and the catalogue features a document pertaining to Zola's capture dated February 1945.
Baron Zemo isn't in the movie...didn't know about the February 1945 document.
