Divya G. clung to a floating banana plant, then used a rope to pull herself to safety through neck-deep water as floods inundated her home in southern India.
After more than a day camped with her family on the upper floor of her neighbour's two-storey house, they were spotted by a fishing boat and rescued.
"We saw a boat coming down our lane and all of us started screaming for help," said Divya, 32, from Chengannur, one of the areas hit hardest by flooding in Kerala state last week. "The boatmen helped us into the boats and brought us to the relief camps."
The worst floods in a century in Kerala have killed hundreds of people, left dozens missing and about a million sheltering in temporary camps. Thousands of army, navy and National Disaster Response Force (NDRF) teams were deployed in the rescue efforts.
Men carry food and water aid distributed to those stranded by floods in Pandanad in Alappuzha district on Tuesday.
More than a dozen rescue officials, flood victims and others who spoke to Reuters said the unsung heroes of the massive relief operation were fishermen and other local people with boats, who volunteered to help rescue tens of thousands of stranded people, often long before official rescue teams could arrive.
"They were in tears when we saved their lives. They treated us like God," said fisherman Stephen Pallithottam, one of hundreds of local boatmen who joined the rescue mission in the Chengannur area. "They touched our feet and said they will never forget us in their lives."
Mohamed Ansheed, whose family was rescued in Malappuram district, some 170 km from Kochi, said he was deeply indebted to the fishermen.
Ansheed also witnessed one rescue in which a local fisherman went on all fours in knee-deep waters, offering his back for women to step on to climb into a rescue boat. Images taken at the scene went viral on social media.
"I will never forget that day. They helped a lot of people," said Ansheed, adding that while NDRF teams had to halt their own rescue missions at sundown for safety reasons, local fishermen worked into the night with headlamps and rudimentary tools.
Many survivors interviewed by Reuters at a Chengannur relief camp recounted harrowing tales of fast-rising floodwaters on the night of August 15.
"It was as if water levels were rising by a foot every five minutes. Even standing on tables or chairs was pointless," said M. Sneha, 20, who was rescued by boatmen that night.
Kerala, which markets itself to tourists as "God's Own Country" and is famed for its scenic lagoons, lakes and canals, has a lengthy coastline and is home to thousands of fishermen and boat tour operators.
The role played by many of them in the rescue operation is now being lauded by both flood victims and politicians.
"The biggest heroes are fishermen, they came in 600 boats and rescued people," said India's Tourism Minister K.J. Alphons, who hails from the state.
Kerala's Chief Minister Pinarayi Vijayan said the state would honour boatmen who participated in the rescue effort, reimburse them, and repair boats damaged in the operation.
Shijin Jose Antony, a priest at a church in state capital Thiruvananthapuram, helped organise the deployment of 130 boats and some 500 fishermen in rescue operations in Pathanamthitta and Alappuzha districts.
"When the fishermen came forward to join the operation, we informed the government, which made arrangements to transport the boats and fishermen to areas where their help was required," he said.
Shiji Dency, a fisherman from Ernakulam district, joined the rescue operation at Aluva and, along with five fishermen from the area, helped rescue about 1,000 people over five days.
Dency says there were no army, navy, or NDRF teams at the location when they arrived.
"We were helped by the local people who were familiar with the area," said Dency, adding they navigated narrow, flooded lanes with cars floating by to reach some victims.
"We are the people in the lowest strata of society," he said. "The people who were trapped in the flood were rich. We felt bad when they pleaded with folded hands to save their lives. It was a heart-rending scene."
