The Last Post Branch is located on the historical site of a Beaver Lumber Co. operation that would ultimately sell the under-performing property to Bob Davidson and his crew of would-be Branch 410 founders. The branch number mentioned here (410), was selected as an ode to the St. Thomas Legion Branch 41, after a meeting between officers from their branch and a group of Port Stanley vets. Bob Davidson and his Port Stanley group requested the blessing of St. Thomas Legion to go forward with the founding of a Port Stanley legion, due to their close proximity. In their meeting, the two groups jested at an appropriate branch number for the new Legion, when one of the St. Thomas officers replied "Oh, that's simple, Branch 41 with nothing added!" and from there the Port Stanley branch number stuck, as Branch 410. As legends has it, the "Last Post" designation was originally suggested by one Steve Stephenson, simply because no other Legion had that name.

​

In 1978, two veterans - Stevie Stevenson and Len Lanley - started a rumour about a new legion. They advertised in the newspaper for all Port Stanley veterans to attend a meeting, to which eighteen attended and would eventually elect Bob Davidson as President, Eric Kipling as 1st VP, Gerte Bowness as Secretary, Wally Johnson as Sgt-at-Arms, and Barb Miller, Stevie Stevension, Glynn Dunn and Norm Barber as other Executives, thus officially forming the Port Stanley Royal Canadian Legion, Last Post Branch 410.
