A starboard side view, taken from well ahead of the beam, of the cargo liner City of Carlisle (1946) bound in, manoeuvring with tug assistance in Tilbury Main Dock. Her bow is out of the picture. The tug Beam (1910), seen from well abaft the starboard beam, is pushing against the liner aft of amidships. The port bow of the tug Challenge (1931) can be seen on the right.
