Elephant swims the River Tamar

Here's an interesting photo from the Western Morning News of Monday 9th July 1923.
Under the headline 'Elephant swims Tamar' is the caption 'Julia, of Bostwick and Wombwell's menagerie, prior to swimming the Tamar, assisted in getting wagons on the ferry at Torpoint.'
It sounds an intriguing story. I'll try to find out more.
Update:
Searching through the newspaper archives, I've managed to find the story that goes with the photo and it's an interesting and comical one:
Western Morning News - Monday 9th July 1923.
JULIA'S BATHE.
ELEPHANT LEAPS FROM TORPOINT FERRY.
During the transportation of Bostock and Wombwell's Menagerie across the Hamoaze on Saturday, Julia, a fine female elephant, suddenly snapped her tether, and smashing through the gates of the ferry plunged into the water. She sank deep and for fully a minute and a half, there was no sign of her. The ferry proceeded on its way and just when hope had been given up, Julia's head appeared and she was seen swimming bravely for Torpoint.
When 20 yards from the shore, she heard her keeper's voice and, obedient to the call, turned and swam back towards the ferry. The tide was running strongly and Julia, battling with the current, seemed in danger of being carried away and drowned.
The aid of a steam pinnace was invoked but the captain, apparently misunderstanding what was required, tried to head Julia back to the Cornish shore. Nothing could persuade her to seek her own safety against the urgent call of her keeper, however, and the pinnace steamed to the ferry and took the menagerie on board.
The elephant refused all assistance but at length the keeper succeeded in lassoing her with a chain and the pinnace stood by.
Julia, never heeding, continued her swim and arrived at the Devonport shore apparently little the worse for her bathe.
