What's this stuff on a tombstone mean?

Friend of my fathers copied the following off his Grandfather's tombstone. Obviously, I can figure out most of it, but I'd like some detail, and I don't want to give him speculation.

2293814
Pte W H XXXXXXXX
CAN CAU BDE
Lord Strathcona Horse
C E

Thanks.

Top line is the Soldiers Regimental Number - 2293814

Next line is his Rank, Initials and Name

Next line should be the abbreviation for "Canadian Cavalry Brigade"

Next line is the Regiment - LdSH (RC)

Next line is Canadian Expeditionary Force, I believe - should have been 'CEF'

Often grave markers will have different units that the soldier served with marked on the headstone.

Canadian Cavalry Brigade
Lord Strathcona's Horse
Canadian Engineers
