The Boom

The boom across the river Foyle was situated some one and a half miles below the city, by Culmore Fort. It's construction consisted of several boats, containing large stones, being sunk in mid - stream. A row of stakes was then driven into the river-bed. Young fir trees were felled and then lashed together to form a boom over quarter of a mile long. Cables over twelve inches thick were used to anchor the boom either side of the river
