Operation Planet, named after the codenames for the attack objectives such as MARS and MERCURY, ran smoothly in the absence of the enemy. Apart from a few mines along the way, the first Canadians arrived in Krabbendijke at 6:05 p.m. There was no time for conversation, as the attack continued without pause. By 8:00 p.m., the vanguard came under enemy fire near Oostdijk. Initially, they thought it was their own artillery, but they were assured that there were no Canadian guns positioned in Oostdijk.

After a brief ceasefire, during which the German defenders retreated, the Canadians reached the flooded polders west of Oostdijk. Further ahead, the road on top of the dyke could be seen stretching as a long, winding path across the vast waterlogged landscape, disappearing into the horizon.

Higher command ordered them to press on without delay towards Yerseke, to cross the South Beveland Canal at the Postbrug or Wemeldinge. Following the sea dyke and skirting the edge of the flooded area, the Canadians made their way towards the fishing village. Without encountering the enemy, the first Canadian soldiers entered Yerseke at 1:50 a.m. on Friday, 27th October. Fortunately, the village was liberated without a fight.

At dawn, patrols were sent out to check if any German soldiers had remained. Two Canadians took a small rowing boat to investigate rumours of Germans hiding in a flooded factory. The water was two metres deep, making the factory hall’s entrance door inaccessible. As an alternative, the soldiers smashed one of the large windows and drifted inside the building. As the boat slowly floated in, they noticed large shelves filled with rows of glass jars. Strange yellow and brown things floated inside the jars, which they couldn’t immediately identify. Suddenly, one of the soldiers recognised the contents and shouted, ‘Holy Mackinaw, they’re full of mussels!’ The first jar had already been opened, and Zeeland's finest delicacy quickly disappeared into the hungry soldiers' mouths. They loaded the boat with their spoils until it was nearly tipping over. They paddled back cautiously. Once they returned to the company, they realised they had forgotten to search for Germans. The scouts kept quiet and simply reported that there was no one in the factory. If any Germans had been there, they certainly wouldn't have posed a threat—they’d have been far too busy enjoying the delicious mussels.
