The Carronade’s Tampion

Earlier this year we announced that a tampion (or tompion) had been brought back to the island after being at the Department of Materials Conservation at the Western Australian Museum for twenty two years undergoing conservation.  This tampion had been discovered in one of the HMS Sirius carronades when it was recovered from the wreck site.   We are delighted to finally have this object on display in our HMS Sirius Museum in a special cabinet constructed by K.C. Industries.



Myra Stanbury, now an 'Honorary Research Associate' at the Western Australian Museum, was the Registrar during the expeditions to recover the Sirius material from the reef.  She travelled to Norfolk in March this year as a guest presenter for the ‘225th Anniversary of the wrecking of the HMS Sirius’, bringing with her the tampion.  She said “In the process of conserving the second carronade recovered from the Sirius wreck site a disc-shaped, lathe-turned wooden tampion (or tompion) was found in the muzzle of the gun. 

Made of maple (Acer sp.), the plug was designed to prevent the penetration of sea water into the bore of the muzzle-loading gun which could cause rust to develop and render the gun unserviceable. Sometimes the tampions were carefully sealed with tallow or putty to make them watertight. This appears to have been the method employed on the Sirius carronade as a ‘waxy-oily’ layer of material was removed from the machine-turned inner surface of the tampion before it was placed in a treatment solution to remove some of the reactive iron corrosion products.Attached to the inner side of the tampion was a lanyard consisting of two 34-cm lengths of twisted twine. This was spliced to a ball of string wadding that fitted snugly within the 131 mm bore of the gun. When loaded with a clean round shot to fit the gun the ball of wadding in the muzzle would prevent the displacement of the tampion by the impact of the round shot as it rolled back and forth in the barrel with every roll of the ship. In this way, sometimes helped by the addition of olive oil or other suitable lubricant into the chamber of the gun, the bore was kept in good condition while at sea”.

This tampion is a very significant object. Not only is it a very rare example of a complete tampion of this period, it is now displayed beside the carronade it was recovered from, and the carronade itself is rare for its early short barreled design –  and it is on display within several hundred metres of the site of its recovery.  Come to the HMS Sirius Museum and take a look for yourself, remember entry is free for residents.   (Our image shows the tampion on display.)



And last but not least, I want to say a huge thank you to two amazing people who have volunteered their time at the museum last week.  Some of you may know David and Michelle Cullen being regular visitors to the island, they have been working hard in the Guard House completing a huge task of sorting papers, creating files and entering data.  I think we’ve exhausted the island’s supply of manila folders.  Thank you, thank you …. and see you again next year.

Touching History

   

This is exactly what 8th generation First Fleeter descendant Andre Forrester did in our museum this week, touched a tangible connection to the history of his forefather.

‘Do not touch’ is a general rule in our museums, particularly when it comes to metal, the moisture, oils and salts on your skin transfer to the object encouraging corrosion.  However, this particular metal object has a sign beside it which reads ‘please touch’.   This object is a ballast block recovered from the wreck of the HMS Sirius during the ‘2002 Sirius Expedition’ the fifth and the last maritime archaeological expedition conducted on the wreck site of this flagship of the First Fleet.  

This iron ballast block has a long conservation story. For many years it has been immersed in a caustic solution undergoing an electrolytic reduction process to remove the chlorides from the metal.  This took multiple changes of more than 120 litres of solution, rinsing and maneuvering of a block weighing in at approximately 100 kg, hundreds of chloride readings and plenty of patience.  Then it was necessary to remove the remaining accretions cemented onto the block, and finally it was ready for applications of rust converters and waxing.  It is these applications and layers of wax that is providing the protective coating that enables it to be ‘touched’.   To list the names of the people that have supported the Norfolk Island Museum with the conservation of this object over so many years, are too many.  However, we’d like to say thanks to Shane McCoy from the Administration Works Depot for his recent work on the final stages and preparation for display.

This is a wonderful addition to our HMS Sirius Museum, housing the most extensive collection of cultural material from the First Fleet.  The First Fleet consisted of eleven ships, nine of these were privately owned and two British naval ships, carrying over 1400 people they left Portsmouth in May 1787 to arrive at Port Jackson in January 1788, these people are the founders of modern Australia.


Andre’s ancestor Robert Forrester was a convict in the First Fleet, making his voyage to Australia on one of the privately owned ships, the Scarborough.  Originally sentenced to death at the Old Bailey for stealing six guineas in gold with a couple of other characters, his sentence was later reprieved to 7 years transportation.  Robert came to live on Norfolk Island between the years of 1791 and 1793 holding a grant of 12 acres at Mount Pitt Path in Queenborough.  Robert Forrester’s descendants have come back to Norfolk to make it their home.  It was an honour to ask Robert Forrester’s descendant Andre to be the first First Fleeter descendant to ‘touch’ this link to his history.

No Ordinary Week!


Tampion removed from HMS Sirius carronade

With the museum being the home of the HMS Sirius collection and last Thursday being the 225th anniversary of her wrecking, this week was never going to be anything other than extra-ordinary! Planning for this day began well over a year ago and teaming up with the Norfolk Island Travel Centre (NITC) meant that Graeme Henderson and Myra Stanbury could be invited to join us from Western Australia as special guest presenters and a full week of events planned. The NITC brilliantly organised a very special week for the First Fleet descendants and others who travelled especially to mark this special anniversary. Visitor numbers exceeded expectations with over 200 people sitting down to lunch and presentations at the waterfront on the anniversary day. 

Myra Stanbury, Kandy Henderson, Graeme Henderson, Kalle Kasi
Graeme Henderson and Myra Stanbury were of course key personnel from the 1980s maritime archaeological expeditions to recover the Sirius’ artefacts that are now on display in the museum. Graeme led the expeditions and Myra was the Registrar. Their presentations underscored the importance of the Sirius (Graeme’s final presentation was titled: Australia’s most important shipwreck) and the story of the undertaking of the 1980s expeditions and their findings. In her final presentation Myra estimated that 50% of the people involved in the expeditions were local Norfolk Islanders. This week brought together the story of the ship and her wrecking, with the stories of the people who travelled on her final voyage or one of the other ships of the First Fleet, as so many of our visitors this week were their descendants.

The relationship the Norfolk Island Museum has had with the Western Australian Maritime Museum (WAMM) has continued from the time of the expeditions. In particular this has been via communication and support with the on-going conservation of the collection. A number of objects went to the Department of Materials Conservation at the Western Australian Museum for conservation and gradually returned to the island when their treatments were completed. Myra and her colleague from WAMM who also travelled to Norfolk for the week, Kalle Kasi brought with them one of the final objects that has been in treatment over the past 22 years. It was an absolute highlight for us to receive the tampion (or tompion) that had been found inside one of the carronades and display it for this week.

Myra has said about the tampion: “In the process of conserving the second carronade recovered from the Sirius wreck site a disc-shaped, lathe-turned wooden tampion (or tompion) was found in the muzzle of the gun.

Kalle, Myra and Janelle unpacking the tampion
The tampion is a very special object. Not only is it a very rare example of a complete tampion of this period, it will be displayed beside the carronade it was recovered from – which is on display within several hundreds of metres of the site where it was when the Sirius was wrecked. 

We have had an extraordinarily busy week at the museum. My sincere thanks to the team of Administration workers employed as our Museum Attendants who have worked so hard to ensure that all our visitors had an extraordinary experience on Norfolk Island this week.
