HMAS Princess Irene (ML-1915)
Back to Commonwealth Ships List
In the real world HMS Princess Irene (I use the name Princess Anne for this
event) blew up at Sheerness in 1915 from an
internal explosion with the loss of 352 lives. A disaster that killed more than
the number of crew assigned to the ship (225). Dockyard workers, other officers
and men down to a girl of nine on another ship nearby died in the explosion.
Because four ships had exploded at or near naval installations the navy
investigated looking for a saboteur. It was not sabotage just accidental causes
leading from mishandling of explosives through lack of training. When a Navy
expands at the rate that the Royal Navy did during 1914-15 then it is quite
possible that some people could end up in positions they maybe should not have.
In my world both HMS Princess Margaret and HMS Princess Irene survive to be bought by the Australis Navy in the 1920's for use in the north to lay mines in strategic places during time of war. Namely between the islands of the Indonesian Archipelago from Sumatra down to Papua-New Guinea. Fast destroyers would do the furthest away while the two Princesses would do the nearer and coastal regions.
Both ships were originally being built for the Northwest passages trade between Seattle to Alaska for a Canadian concern. Requisitioned in 1914 the three ships were converted to auxilliary minelayers with a large mine deck being cleared where cabins had been previously. A slot on the stern being opened and covered with doors to allow the mines to drop into the wake of the ship.
Refits through to 1938 added little to the ships, but it was decided to give the ships a decent overhaul to fit them better for their main purpose. To this end Asdic was added so that the minefields they were laying and tending could be plotted more precisely and make it better for the Allied ships to pass through. Added to the Asdic for plotting was a strong short ranged Radar (mounted above the bridge) for taking readings off the nearby landmarks. During 1940-41, further Radar and other electronic devices were fitted to the ships.
The outbreak of war found the ships with the main fast fleet at Darwin. The
ships were transferred to the Mediterranean Fleet where they began to lay
defensive fields around the entrances to Alexandria and Malta Bases. The ships
speed was also useful when they were used twice
to take essential supplies to Malta with other fast merchant ships. With the
entry of Japan into the war, the ships were withdrawn from the Mediterranean,
and sent to Darwin where they were filled with mines and sent to do their prime
directive - mine the passages through the Islands of Indonesia. This lasted one
mission with the Japanese advancing so fast, and the disasters in the Java Sea,
the Australis Navy forces were forced to retreat again and again.
Both ships were used in the evacuation of Singapore where the mine deck and
other cabins provided temporary accommodation to many hundreds of civilians then
military personnel. Neither ship was used for their primary purpose after that.
The big mine decks being used for carrying urgent stores to the various bases
around the Western Pacific. It was during one of those missions that the
Princess Irene was torpedoed. The Princess Margaret had been used during 1942 to
1944 as Escort command ship for the Australis convoys supplying its forces
acting with the US forces through the Island hopping campaigns. Both ships had
been fitted with Hedgehog spigot mortars for ASW work in 1942, Princess Margaret
participating in the sinking of two Japanese submarines in 1943, being credited
with a half and a quarter result along with other escorts of the group.
The mine door is visible at the stern of HMS Princess Irene.

Original drawing of Princess Irene, must have been one of my first. Guns out of place, wires not reaching their destinations, all sorts of errors. And those horrible funnels (shudders).
