It happened on Monday and the area has now been cordoned off until it can be repaired.
Community councillors are hoping that it will be fully restored quickly and member Carol Rogerson has already written to Dumfries and Galloway Council asking for prompt action.
She said: “I am worried it does not get repaired to the same standard it was. I would imagine they will have to take it to pieces to see the extent of the damage and then rebuild it, it will need a specialist builder.
“We want it restored to how it should be – and by November would be ideal in time for Remembrance.”
Carol also pointed out that the original ironwork was painstakingly restored last year by her husband, Andrew, and is quite rare, so she hopes it too can be salvaged.
The memorial was erected after World War I and features names of soldiers from the royal burgh who fought in both World Wars.
It is looked after by the community council and they were planning to enter in in a competition, after enjoying success in last year’s British Legion centenary contest to find the country’s best war memorials.
However, Carol said: “Obviously that’s now been hit on the head.”
