Would the army land before the naval battle ended?

Could the landing proceed while the Royal Navy was still preparing for the German fleet?

The British would begin unloading almost immediately because troops ashore create the political and military pressure that forces Germany to respond.

The transports would probably begin landing as soon as the fleet reached its objective. Waiting for the fleet action to end would surrender surprise and leave the operation without its land anchor. Troops ashore also make the threat to German territory unmistakable. That pressure helps compel the High Seas Fleet to leave port and fight. The landing and fleet action support each other as parts of the same operation.
