In 1943, a German Bomber plane was hit whilst on a bombing mission to Liverpool. All 5 crew perished.

Could it be this one? Can you just make out the Marble Church spire towards the bottom right of the picture?

In 1919, a group of Canadian military recruits went on a riotous rampage. During the overnight battle, many perished, including 5 Canadians held responsible.

Perhaps this one...it seems a little far-fetched but...?
