A remarkable rescue operation unfolded along the Thames River recently, following the stranding of a pod of 27 pilot whales. The incident took place on 19 September, prompting a significant response from various marine rescue teams and local authorities who worked tirelessly to guide the whales back to the sea. Harbour master Lyn Kindlen from the Port of London Authority, who played a pivotal role in the operation, described it as one of the most unusual and memorable events of her career.

The saga began the day prior when the Port of London Authority alerted the public about the whales spotted in the river, specifically near Gravesend. The authority asked onlookers to avoid the area to prevent causing additional stress to the already disoriented creatures. Pilot whales, often mistaken for dolphins, were first seen by Marine Pilots who reported their unusual presence in the tidal waters.
According to Kindlen, the immediate challenge was to manage the confusion among the whales, which were spotted moving erratically. “They were very confused; you could see they were heading off in all different directions,” she mentioned. The operation required a great deal of patience, as rescue teams needed to frequently reassess the situation while navigating the busy shipping traffic in the river.
As part of the rescue efforts, crews from the British Divers Marine Life Rescue (BDMLR), alongside local authorities from Gravesham and Thurrock, collaborated over the weekend to form a plan that would safely lead the pilot whales back to their natural habitat. “These creatures are beautiful, but their presence in the Thames raises serious concerns for their welfare as this is not an environment conducive to their survival,” the Port of London Authority noted in a statement.
On the morning of 19 September, a well-coordinated operation commenced at around 7 a.m. with experts utilising eight vessels to assist in escorting the whales out of the river. The operation was complex, spanning approximately 20 nautical miles and lasting for six hours. It became evident that the rescue would take longer than anticipated due to certain whales being mothers with calves, who required breaks during the journey.
Regrettably, not all of the whales made it through the operation unscathed. Two of the pilot whales were reported to have died during or shortly after the rescue efforts. One whale showed concerning signs of unwellness and washed up on the shore, while another was able to return to the water but subsequently succumbed later that day. In response, the Port authority is collaborating with BDMLR and the Cetacean Strandings Investigation Programme (CSIP) to recover the deceased animals and conduct necessary autopsies.
Reflecting on the operation’s outcomes, Kindlen expressed pride in the unified effort to save the remaining whales. “Herding a pod of lost pilot whales is not something I have ever done or thought I would end up doing! Seeing these animals up close was just incredible,” she conveyed. Furthermore, she praised the collaborative spirit demonstrated by various teams that sprang into action at short notice, ultimately ensuring the successful rescue of 25 whales from a dire situation.
Although the immediate threat to the pilot whales has now subsided, the Port of London Authority has advised the public to remain vigilant and report any future sightings of whales in the river. The Thames, with its shallow waters and limited food supply, is not a suitable habitat for such marine mammals and any recurrence could lead to similar incidents in the future.
As the river is believed to be clear of the pilot whales for now, the rescue operation serves as a reminder of the challenges faced by marine life in urban waters and the importance of collective response efforts in preserving wildlife in unexpected situations.
