Trace a D-Day landing ship through operational records

Where can a researcher find the load and unit carried by a particular landing vessel to Gold Beach on D-Day?

Start with the D-Day landing records at the United Kingdom's National Archives, some of which may be available digitally.

The viewer wants to identify the unit carried by a vessel numbered 287 to Gold Beach on 6 June. The starting point is the D-Day landing records held by the United Kingdom's National Archives, some of which may have been digitised. This is a primary-source problem because the desired link is between a particular ship movement and a particular embarked unit. Beginning with the vessel number, beach, and date gives the archival search the precise operational identifiers supplied in the question.
