[underlined] GENERAL STATEMENT. [/underlined]

A re-examination of the photographs taken after the daylight attack on the Dock Area of Boulogne on 15th June, 1944 by aircraft of Bomber Command confirms the damage and destruction of shipping and port facilities and devastation of parts of the town reported in Immediate Interpretation Report.

A more detailed study, however, has shown that some 25 vessels are damaged or sunk in water shallow enough to permit interpretation, and that of the nine E/R boats visible on 15th June before the attack, only one, and that probably damaged, is seen on these photographs taken two days later. Sheds in the boat building yards and warehouses in the immediate neighbourhood of the docks have all been damaged and the dock walls and quays breached in many places.

A large Brick and Tile Works, two ice factories as well as other small industrial concerns are seen to have suffered damage. The Town Gas Works and an Electricity Sub-Station have also been affected.

1. E/R Boat Pens Section of Quay destroyed; 1 crater in roof, possibly penetrating and 2 or 3 blast areas on roof.

2. Building of similar construction S.W. of E/R Boat Pens. Non-penetrating blast area on roof due to direct hit.

3. Three Oil Tanks W. Of Pens - all 3 destroyed.

4. Defended Area - numerous craters.
