Below is a brief excerpt from the document, it does describe everything that happened in the link above

3 June - Force 'U' officers further briefed. Crews briefed
aboard their craft. Craft got under way, but bad
weather forced postponement of the Operation.

4 June - Craft again got under way.

6 June - From about 0200 on, craft arrived off coast of
France. NCDUs and Army Demolition Units embarked in
their smaller craft. Boat Team #6 had made almost
entire crossing in their LCM when LCT (HE) 2075
foundered; Boat Team #2 had embarked in LCM at
2300 and cast loose at 0330, when LCT(A) 2227 was
crippled by flooded engine room; and Boat Team #11
had to abandon their LCT at 0200, in sinking condition.
Foundering of 2075 was result of water coming
in where starboard rail had been out away and replaced;
replaced section swung one way only, like a
valve, admitting water and then impounding it. The
Assault Units of Force '0' went ashore to fulfill
their mission after almost a week aboard LCTs (whose
decks were often awash), having had no hot food or
exercise. Support NCDUs of Force '0' were fairly
fresh after crossing on LSI; and NCDUs of Force 'U'
had been on LSTs. It is felt that use of LSTs, if
available, is preferable.

The story of the actual operation is told in Section
II.
