While one of the main focuses of the Governments of the European Powers in seeking to pacify Crete was the provision of sufficient naval forces and infantry to keep the warring factions apart, they were also faced with the fact that the Cretan Christians also had artillery at their disposal. This was highlighted when Rear-Admiral Harris, the then Senior British Naval Officer on Crete, referring to the evacuation of Greek troops from Crete in May 1897, reported:
‘The question of artillery has given much trouble. It was obviously most undesirable to have guns left behind in the hands of the insurgents when the whole object of the Powers is to pacify the island. After much trouble and insistence on the part of the Admirals, four of the six guns stated by the Greeks to belong entirely to the Cretans are to be embarked with the Greek troops, the other two are said to be on Akrotiri, and the Admirals have made a peremptory condition that they also shall be taken away.
The western end of the island will then, I believe, be free from insurgent artillery; though we know that there are four to six 7-centim. Krupp guns to the eastward, we cannot immediately connect them with the Greek troops or Government, though there is not much doubt that they indirectly or otherwise provided them.’
In the end, the Royal Navy oversaw the evacuation of 6 field guns, 12 horses, 53 mules and 233 cases of artillery ammunition.
(An internet search suggests that although described by the British as 7cm (70mm) there wasn’t a 70mm Krupps gun at this time: the pieces in question could possibly either have been 65/66mm guns or 60mm mountain guns. To add to the confusion, the Ottoman Empire was, at this time, the world’s largest importer of Krupp guns, purchasing 3,943 Krupp guns of various types between 1854 and 1912.)
To counter the threat of Greek/Cretan Christian artillery, in the early stages of the Intervention, both the Powers and the Ottoman military supplied artillery to the island.
An illustration from an Italian magazine shows Ottoman artillery beneath what is apparently an Italian flag.
It would appear that the French forces also had access to artillery, whether their own, Ottoman or that landed from H.M.S Anson. Captain Egerton recorded that:
“Last night [10th April 1897] at 6.30 p.m. the International Force at Soubaschi fired 5 shots from the 9 pdr. The fire–eating Perignon[?] who commands will someday if he irritates these fellows too much, bring Vassos about his ears – Vassos’ outposts are only about a mile away. – G.E. “
In addition to the Royal Artillery Mountain Battery stationed in Crete in the early stages of the Intervention, following the events in Candia in September 1896 the Royal Navy reinforced the town, landing field artillery.
