Lamentably

He fell lamentably short of his duty.

Lamentably, the findings from yesterday were like you see them.

The cattle were heard lowing most lamentably, several of them were seen wandering and running about in disorder and the shepherds believed that these were lamentations and marks of sorrow for their departed master.

The court there commented that "the decisions of the common-law courts have been lamentably conflicting" on this point and stated that it did not have room to list the "vast number of inconsistent and almost contradictory cases upon this somewhat confused branch of the law".

Lamentably the good too die; we will all mourn his passing.
