While temperance activists bombarded soldiers with pamphlets about the evils of alcohol, the votes of 30-40,000 New Zealand troops overseas prevented prohibition succeeding in 1919. While many warned that use of illicit drugs would replace alcohol if prohibition was enacted, soldiers always had access to a range of intoxicants. German soldiers were stimulated by "Pills to induce bravery"; the Anzacs were given cigarettes and coffee - both stimulants - and drank a rum and tea or coffee concoction called Gunfire Breakfast. Chewing tobacco was one of the drugs used by some returning soldiers in 1917 Christchurch to cheat their medical test so they wouldn't have to re-enlist.
Three weeks before they landed at Gallipoli, 2500 drunken Anzac soldiers rioted in Cairo. A 1918 Oamaru Mail letter writer complained of "recent drunken orgies at the Anzac dinner" following an aborted April 1918 gathering for 800 returned soldiers.
The letter writer said while German militarism must be fought, "the sooner we get rid of the enemy within our gates the sooner will victory be ours".
While Australia's Federal Government took action to treat widespread alcoholism among returned soldiers in 1919, New Zealand didn't follow suit. As Dunedin's Reverend R. E. Davis said in a debate of 1916, "there is an appetite for liquor in New Zealand that would defeat any law".
Private Reuben Baldwin had the appetite. An inquest attributed his death to chronic alcoholism.
He'd been laid off or expelled from the army in August 1918 following six months of constant trouble and punishment, including drunkenness, abuse and "offering violence".
Reuben Baldwin is buried at Hawera Cemetery and commemorated at Auckland War Memorial Museum.
