However, Hardy would soon move on to a decade at Aston Villa. Thus at just twenty Campbell for much the same period of time become Anfield's regular between the posts, his time there, of course, interrupted by The Great War, during which he served in the Royal Garrison Artillery, stationed at Crosby, but including marriage to Constance Warnock in Birkenhead and starting a family. They were to have three children.

And he also had his arm lengthened, paid for by the military. Thus far he had played with one arm longer than the other. And the operation seems to have worked a treat. In early 1920 he would be called up by Scotland, at Liverpool at first, twice, and then the following season six times more at Partick Thistle, which in 1921 he would captain to the Scottish Cup.  However, during the period his wife and children had remained South and in 1922 he returned to Merseyside to join nearby New Brighton for a year outwith the League. And he also opened a sports shop in Wallasey that he would run until retirement from the business, whilst in the meantime spending more six years back in League action with Stoke and Leicester and a final two seasons back at the local club.        

In fact, retirement from work would be late, into his eighties, by which time he had in 1964 lost Constance. And he himself would pass away in 1977, aged eighty-four, whilst living with his son, to be buried still locally in Wallasey Cemetery.
