Learning curve or Am I just that stupid?

[Cats]

New guy here,

I have been playing war games for a little while. Some of them have been a challenge to learn but I have just plain struggled to understand Gallic Wars.

I have been trying small scenarios where I can move small formations and last night just about sent me over the edge. I was using 003_Gallic Raiding Party. I had my heavy infantry in line (not stacked) with 2 companies protecting my only exposed flank. It looked like a J. Had skirmishers out front, leaders behind the HI. Had 3 squads of HC ready to sweep down in the flanks of the barbarians who were doing a frontal attack.

At the start of the turn I had 98% Happy troops, 0 routed, 1 disrupted.

At the end of the turn I had 4 routed, 6 disrupted and my happy troops were down to 53%.

Next move I was toast...........

I have read all the files and am trying all the moves. I just don't get it.

Is anyone else struggling with this game?
