I think it would have made very little difference to the overall outcome of events.

Two events would not have changed:
1. The Great Storm.

This would have left the British in Caen with a larger rear area to hold and with less reserves to hold out with. A longer 'front' would require more defensive measures as any offensive action would not be possible without those supplies held up after the Great Storm.

2. The American breakout.

This would not have happened any sooner. Until the Americans could break out of the bocage, no broad front offensive action could happen.

Add to this there would have been none of the 'racecourse' attacks and with that no gain in battle experience. The British would have been unable to advance without creating a problematic salient which could result in a German attack between the British and American sectors and this would lead to a defence strategy and mentality. Dangerous in the circumstances.

Then we need to examine the real reason for the German defeat- the Mortain adventure in which most of the German offensive and therefore defensive strength was wasted. It was here that German hopes of remaining in France faded and it was only after this oint that German forces retreated out of France.

But consider a British Drive to Falaise in June or July while the Americans are held back. Now you have one force moving east and the other stationary with not much in the area defending the port.

Cherbourg was no prize, nor was Brest but the Winston docks at Arromanches were vital for success. Any German drive there would have resulted in terrible consequences if successful.

or.......

Without British pressure on their front, the Germans could reinforce their positions facing the Americans without a need for any serious expenditure of armour while concurrently preventing any hope of an Allied breakout.

Caen was a convenient point on a map to draw a line through and name as a primary objective but as we know from other adventures, capturing cities is not the best or most useful event to drive towards, see Leningrad, Stalingrad or...... Paris for that matter.

Ultimately, the plan worked, the Seine was reached within the 90 day plan and supplies advanced on schedule.

Caen was of little importance in the end.
