Colonel Gibb died, at his home, "Roslyn," Keyhaven Road, Milford, on Sunday 20th August 1933 at the age of 74. He died from contracting a severe chill after returning home from a holiday in Wales. He had resided at Milford for about 20 years, and although he never took an active part in the public life of the district, he will be greatly missed by a very wide circle of personal friends, by whom he was held in affectionate regard.
Following Colonel Gibb's death the Regiment received the following letter from Colonel Edwards, living in New South Wales, Australia at the time:
"I can only recall to mind six of those of the old 29th Regiment who were contemporaries of Colonel Gibb in 1879 and 1880 and who are still to the fore. In those far-off days we youngsters were fairly shrewd in summing up the qualities of each other, and we were from the first impressed with Jack Gibb whom we labelled as one possessed of grit and determination. An exploit of his when on his way up from Bombay to Mhow to join the 29th appealed to us. He was detained for a few days at Deolali, a big Rest Camp. As orderly officer of the day he had to visit any prisoners there might be confined n the cells; with the Provost Sergeant he came to one occupied by a Gunner who had been sentenced by court-martial to be discharged with ignominy. The prisoner, on Gibb reaching his cell, commenced a volume of guli bat. When asked, the P.S. stated that every day the prisoner swore at the officer in similar language. Gibb took off his coat, rolled up his sleeves and told the Sergeant to open the cell door ; he then walked into the cell and told the occupant to put up his fists.
Colonel J. H. S. Gibb, D.S.O.
