Panther Hunt gone wrong- first crack at KGN

We had our first crack at Kampfgruppe Normandy using the full rule book - as opposed to a reference sheet I downloaded- it was great fun. Unfortunately it was a debacle for my Wessex boys & their 8th Armoured Brigade support.
 However, I think we may have stuffed up the Line of Sight rules- I had another looking the morning after- we were doing direct fire at things that were concealed behind bocage etc, and thought that the spotting rule was sufficient, even though they were not visible by line of sight. I understand the specualtive nature of suppressing fire, but I think that unless your chaps can make out where the enemy actually are by line of sight, then direct fire is not possible- particularly when it comes to Anti-Tank actions. Perhaps someone could clarify this for us.
My opponent was the Red Rajah and his Kampfgruppe. Our forces are a combination of metal, plastic & resin. Enjoy the pictures.

 Might have gone wrong at this point re direct fire and line of sight, as there's quite a bit of bocage between them?!

Good Night Achilles!

What was left of the British HQ section after....

....this German MG team mowed them down.

The one British success, storming and clearing the orchard of Germans.

Oh dear, there go my Shermans, falling prey to the Panther & Pak 40.

At this point we decided to call it a night, besides the pizza had arrived & the ladies wanted the dining table back! I picked up a total of 8 points of moral counters, as opposed to Red Rajah's 4. The British withdrew with the remnant of their force, considering how it would be good to have some 25 Pdrs for next time!
