S142 Double shot, position 80, forward speed 5 naut. mi., missed fore. Single shots, position 100 (110), forward speed 3 (1) naut. mi., missed.
Stopped square 2364 right top side, conferred with S142. I presume reason for misses is the varying slow speed of the vessels, but do not exclude the possibility of shooting under them (land craft tanks). 2 torpedo detonations observed on land.
Short code message received: “S140 report position. 5th E-boat flotilla.”
Short code message sent: “Convoy course south. S140.”
Proceeded at 24 knots, 125 degrees to attack with artillery fire.
Attacked firing all arms at the two vessels lying to the north, range 600-300m., our speed 24-9 knots. 60 rounds of 4cm ammunition fired per boat. Good position for hits, no return of fire.
Steered to 260 degrees via north. 36 knots. After 4 minutes I interrupted the fire, which was intended to show the other boats the position of the convoy, in order to permit them to attack without confusing them. Therefore
Short code message sent: “My position is 2365. S140”
Short code message sent: “Return commenced. S140.”
Radio telegraph message sent: “Convoy of three coast steamers. S140.”
No more vessels and steamer of the convoy were seen. The three vessels must have been the rear of the convoy and separated from the rest.
Square 2367 top left sighted white flashing buoy (AN), Square 2383 bottom center lighted buoy (F.w.).
Square 2397 – steamer shadow off port bow. 36 knots west, then changed course from 10 to 10 degrees [typo?] through 140 degrees. Until

Passed Cherbourg jetty upon return.
Lieutenant and commanding officer S140.
