For those that have been playing West Front for awhile, I created an Operation Sealion scenario 13 years ago. You can find the revised version at the following location. It has been updated to current 2.02 standards utilizing some of the new features and units. The map has been expanded to the south a bit, but otherwise most of the unit placements are identical to the original version.
Operation Sealion 2015 Version
[Hypothetical: 20150411 Version]: Kent County, England: [Best
Played against Human Opponent or as Team Game]: As dawn breaks
on the morning of July 14th, 1940, so does the silence along
the east coast of England. Parachutes open and fall towards the
ground below. The sea churns up a vast armada of water craft
carrying the initial landing forces of the German Army, with
one goal in mind. Establish a beachhead and breakout into the
countryside en route to London to seize the capital. Hitting
the beaches were the 17. Infantry and 6. Mountain Divisions landing
along the coast between Hythe and Dover. Dropping behind the
coast, the 7. Flieger Division to secure the nearby airfields
and help establish a beachhead. Defending the coast were elements
of the understrength 1st London Division, a number of Home Guard
battalions and assorted coastal batteries. The British beleived
the attack would come along the east coast and had the quality
units stationed up north. The difficult task at hand for the
1st London Division was to hold up the German attack long enough
for reinforcements to throw the German invaders back into the
sea. [NOTE: This is an updated version to the Matrix Campaign
Series West Front 2.02 standard. NOTE 2: This scenario is based
on the Kenneth Macksey "Invasion" book.][2.02]
