Recruitment in the Field
Units can be recruited directly by a general in the field, although only those troop types available in the province he is currently standing in are displayed - it is not possible to draw in recruits from other provinces. Select the general and then the recruitment tab that appears next to his portrait, then left-click on a unit to add it to the queue and once again to remove it. When ready, units will walk to the appropriate general and merge with his army. Note that units can only walk directly to the general, they are not able to cross the sea to join him.
