Also, small question, a blockade is just blocking all adjacent sea tiles, or completely surrounding the city with units. Because I'm not getting blockades in the first case.
I believe, for purposes of city combat modifiers, a blockade involves occupying all adjacent land tiles and blocking all adjacent sea tiles (which can be achieved without having a naval unit on every tile). (Mountains count as blocked tiles; I can confirm.)
For purposes of "City connection"
