269 Sqdn: 21 or 22/06/1940 attack on Scharnhorst?

According to the 269 Squadron Old Comrades Association - http://www.oca.269squadron.btinternet.co.uk/history/squadron_history/chronology/1936-1940.htm - Hudsons of 269 Squadron attacked the Scharnhorst on 22/06/1940, together with Beauforts of 442 Squadron. Obviously 442 sqdn = 42 Sqdn (or perhaps 224) but...

42 Squadron lost 3 Beauforts in an attack on the Scharnhorst on 21/06/1940.
Two Hudsons of 224 Sqdn and one from 233 Sqdn also attacked the Scharnhorst on 21/06/1940.

Does anyone know if these were three different attacks on two seperate days, or was the attack by 269 Sqdn also on 21/06/1940?
