Sinking of Janequeo and Leucoton

On 15 October 1965 the Chilean sank off Caleta Llico, south of Corral, Chile, with the loss of 51 men.
 under command of Pedro Fierro Herreros was ordered to the periodic maintenance of the lighthouses but on 2 August, as bad weather threatened the ship, they were forced to take refuge in "Caleta Manquemapu" within "Bahía San Pedro". As the anchor chain broke, the ship ran aground. The naval authorities immediately sent "Janequeo" under the command of Marcelo Léniz Bennet, to free "Leucotón". On board was a rescue team of fixed men under the command of Claudio Hemmerdinger.
The crew of "Leucotón" made it safely to shore but despite days of effort, she could not be freed.
At 16:00 on 14 August a tow line got entangled in the propeller of "Janequeo". Despite the intensive work of Hemmerdinger's frogmen, it was not possible to free the screw. "Casma" and "Yelcho" were now ordered to the rescue, but they could not enter Manquemapu Bay, due to waves over high. That day "Janequeo" repeatedly struck the rock "Campanario", and although still afloat, was partially flooded.
At 9:20 on 15 August "Janequeo" broke in two. Only 28 men of the crew survived and made it safely to shore, but 51 men were lost.
Aftermath.
On 15 September 1965 appeared the first edition of the Chilean magazine "Punto Final" with an analysis of the disaster of "Janequeo". Journalist Miguel Torres accused the admiralty of the Chilean Navy for the disaster.
The "Leucotón" shipwreck is still rusting on the beach of Manquemapu.
The patrol boat "Fuentealba" (15 t), the landing ship "Hemmerdinger" (1500 t) and patrol boat "Odger" (215 t) of the Chilean Navy are named after three of the sailors who died in the disaster.
