CS Forester once had his fictitious naval hero, Captain Horatio Hornblower, RN, legging a canal barge through the Sapperton Tunnel. Even Hornblower, victor of a dozen desperate sea battles in Nelson’s navy, would be hard put to force passage today – roof falls have blocked the tunnel and severed the Thames & Severn Canal, a through route between London and the west coast of Britain in former times.

These days the wonderfully ornate southern portal of the Sapperton Tunnel looks out on a silent waterway, weed-grown and melancholy in its shadowy cutting. We passed a strange little round stone tower, once the abode of a canal maintenance man, and turned down a side path fringed with cowslips to Trewsbury Mead and the source of the River Thames.

Old Father Thames in infant form whelms from a little circle of greenish stones near an ancient ash tree. At least he does in wet seasons – today in Trewsbury Mead not a trickle disturbed the grass. Strange to think that, 180 miles to the east, this modest nothing of a river would be coursing through London before broadening out to meet the North Sea.

St Matthew’s Church in nearby Coates lay quiet and cool. From a memorial display a rather severe face looked out under a military cap. Lt Col Bernard Vann, raised as a boy in Coates Rectory, was the only C of E clergyman to win a VC as a combatant in the Great War. His decoration, for leading a charge against German positions under heavy fire, was a posthumous one. His wife was one month pregnant at the time of the attack, but neither she nor Bernard was aware of that, when a sniper killed him four days later – five short weeks before the end of the war.

A flood of bluebells splashed the floor of Hailey Wood. We turned down a broad ride between log stacks. Badger highways had been beaten out by leathery pads through the undergrowth.

Beyond the wood we climbed through a bright gold sea of oilseed rape to the great barn and chapel at Tarlton Manor, a dream of mellow perfection in Cotswold stone, before dropping down across a green and gold valley to the Tunnel House Inn and the ornate portal on the old canal once more.
