Very cold, dull. Out only to feed Fluffy in evening. Warning 9.25 to 10.00 a.m. thence on and off all day from 10.30 a.m. to 5.20 p.m. Sound of many planes and gunfire. One plane dived out of the clouds to 300ft. using its machine guns. The local battery let fly but I think it got away.
On this day: Germany warns that any ships taking supplies to Britain would be torpedoed.
