The regimental march of the British Army's Corps of Royal Engineers, amalgamated from two older tunes in 1870. Exactly when it was adopted by pipe bands is unknown but was being played by army pipe bands well before WWI.

It was originally scored by Bandmaster Newstead of the Royal Engineers Band to combine two tunes; one being from the air "The Path Across the Hills", a tune of unknown German origin, and the other Wings, a contemporary popular song by Miss Dickson.
