Jam Tins On The Wire

I’ve never read of this before until I came across in R. Hugh Knyvett excellent book: "Over There with the Australians.”

There must have been plenty of used jam-tins and the noise of the tins on the wire would have been very unusual.

“There was another use made of empty jam-tins: they were tied to our barbed wire so that if any Turk tried to get through he would make a noise like the cowbells at milking-time. Talking about barbed wire, Johnny Turk played a huge joke on us on one occasion. As the staking down of wire was too risky, we prepared some "knife-rests" (hedges of wire shaped like a knife rest) and rolled them over our parapet, but opened our eyes in amazement to find in the morning that they had only stopped a few feet from the Turkish trenches. The Turks had sneaked out and tied ropes to them and hauled them over to protect themselves. Thereafter we took care to let Abdul do his own wiring.”
