The Wooden Horse

The vaulting horse provided perfect cover for the tunnel entrance because it was a lightweight, plywood structure that could be carried daily to an open area near the perimeter fence. The Germans would never suspect that prisoners were digging directly in the middle of an exercise field, especially beneath a gymnastics apparatus. The horse allowed the digger to work hidden underneath while other prisoners exercised above, creating a seemingly innocent routine.

The decision to use the vaulting horse was inspired by the camp's location, the open area near the fence offered the only viable path to freedom.

They maintained absolute silence on the surface and filled the tunnel aperture with wooden boards and sand at the end of each daily session. The key was using dry sand, which matched the ground color, rather than wet sand, which would appear darker and raise suspicion. The operation required two men hidden inside the horse while a larger group performed exercises above, creating a convincing cover for the digging noise.

The meticulous daily routine of carrying the horse out and back was established from the very beginning to normalize the activity.

The sentry discovered the hidden men while they were concealed at the dock, presenting an immediate threat to the entire escape operation. With no time to flee or bluff their way out, they had no choice but to kill him to prevent being captured and potentially revealing information about other escapees. This desperate act underscores how perilous every step of their journey was.

The filmmakers earlier established that capture meant execution, raising the stakes for every dangerous encounter.

Each escapee took a different route to minimize the risk of all being captured together. Phil disguised himself as a Norwegian margarine salesman and traveled alone by train through Danzig, while Howard and Clinton headed toward Lübeck. This variation in plans meant that if one route failed, the others might still succeed. Phil's cover as a neutral-country salesman allowed him to pass through checkpoints more easily.

The escape plan always included multiple breakout routes to improve overall chances of success.

After escaping the camp, Howard and Clinton traveled by train toward Lübeck, then made their way to the Baltic docks where the confrontation with the sentry occurred. They then contacted French workers who connected them with Sigmund, a Danish resistance contact. Sigmund smuggled them onto a Danish ship, from which they transferred to a fishing boat that took them to Copenhagen, and finally to neutral Sweden. Phil arrived in Sweden earlier, having traveled separately via Danzig.

The resistance network was established early in the planning as a critical component of the escape route.

As the tunnel grew longer, the physical demands of the operation became too great for just two men. The digging required someone to work inside the tunnel while others managed the cover operation above, and the workload was simply too exhausting to sustain with the original team. Phil was recruited with the promise that he would be included in the eventual escape, becoming an essential part of the daily operation.

The plan always anticipated needing more hands as the tunnel extended beyond initial expectations.

Each day, the team carried the vaulting horse to a fixed spot in the open area, creating a believable exercise routine that justified their presence. One man hid inside the horse structure to dig while others performed vaulting exercises above, masking any sounds from the digging below. At the end of each session, they placed boards over the entrance, filled it with sand, and carried the horse back to the hut, making the entire operation appear completely innocent to German guards.

The regimented daily schedule was designed to become so ordinary that guards would stop paying close attention.

After the dangerous confrontation at the docks, Howard and Clinton connected with French workers who introduced them to Sigmund, a Danish resistance collaborator. Sigmund guided them onto a Danish ship and coordinated their passage to Copenhagen, arranging their eventual transfer to a fishing boat heading to Sweden. Without this resistance network, the escapees would have had no safe way to cross the Baltic Sea to neutral territory.

The escape plan anticipated needing civilian help once outside the camp walls.

During the final breakout, Clinton hid inside the tunnel during the evening Appell (roll call) to avoid detection while the others prepared. When the moment came, three men were carried out inside the vaulting horse, a third man stepping in to replace the tunnel trap that had been keeping the entrance sealed. This daring execution allowed Howard, Clinton, and Phil to all escape together, though they would later split up to minimize capture risk.

The final escape required perfect timing between the man hidden in the tunnel and those carrying the horse out.

Taking separate routes was a deliberate strategy to maximize the chances that at least some prisoners would make it to safety. If all three traveled together and were captured, the entire operation would fail. Phil traveled alone as a Norwegian margarine salesman through Danzig, while Howard and Clinton went toward Lübeck. Each route posed different dangers, and the split reflected the prisoners' careful planning to avoid putting all their chances in one basket.

The decision to split up was established as part of the original escape plan.
