Returned Services League (RSL)

The Mount Pleasant Returned Sailor's & Soldier's Imperial League (RSSILA) was formed on 3 July 1920, with Hartley Williams as President and Willie Ross Smith as Secretary, as well as Elliott Murray of Rhine Park amongst the members. This arrangement did not appeal to the ex-soldiers in the region who tended to socialise at Gumeracha as the Upper Torrens Valley Sub-branch until 1928, after which local ex-soldiers began meeting informally at Mount Pleasant. With the blockers at Jutland the membership reformed a permanent club in the region. A new charter was presented in April 1930 by State President of the RSSILA Lieutenant-Colonel Walter Dollman.

Meetings at the new Soldiers' Memorial Hall at Mount Pleasant were liquor-free evenings of bridge and euchre, which did not appeal to the survivors of Gallipoli and Flanders who were now hard-working blockers. Members tended to venture to the hotels at Mount Pleasant and Springton. The group challenged other Sub-branches in games of cricket, held annual dinner dances and socials, and hosted seasonal picnic and Christmas tree parties for the children. The annual Anzac Day services officiated by a local clergyman was held at the Soldiers' Memorial Hall at Mount Pleasant.

In 1934 the Mount Pleasant RSSILA Sub-branch offered to plant trees that led to the showgrounds from the main street to commemorate the World War 1 dead and suggested the street by named Memorial Avenue. Doctor Cowling donated the saplings and the Sub-branch hired labour to dig the holes ready for the planting. The ground proved almost impossible and further funds were needed to finish the required digging. Name tags were placed at each tree, but have long disappeared.
