Boarding a Fleet
Board a fleet at a coast by left-clicking to select your army or agent and right-clicking to move onto it. Note that it is not possible for a boarded fleet to leave port until the beginning of the following turn.
Disembarking from Fleets
To disembark an army or agent onto land, select it and hover your mouse over the coast. The cursor will change into an arrow with a figure - illustrating that the army or agent can be disembarked. Right-click to disembark. Disembarkation also works by left-clicking and dragging the army or agent onto the land. Ctrl + A to select all units or agents on a tab.
