Tutorial question

[type7]

In the first tutorial, when it tells you to

Merge the units from Nashville with the Corps of General Sherman. Add the '1st Col. Brigade', the 'Kentucky Volunteers' and the 'Nash Artillery' to the Division of General Pentiss(6th Division).

How exactly do you accomplish this? I can drag those units to Sherman's corps just fine, but I cant drag the units to the 6th division within Sherman's corps. Do I need to split the 6th division and reassemble it? Or am I missing something?

Hi type7!

Add units to a division:
Select the division and the units you want to add. (Hold the 'Ctrl'-Key to select multiple units). Now press the 'Combine' button (marked with a '+').
The units will be now added to the division.

Ahhhhh Thank you very much

I suppose actually reading the manual would provide me with that answer too
