From the caption of AWM. Footsore, unshaven and very tired, this is how four sergeants returned to their base after “walking in” from Tobruk, Cyrenaica, Libya on August 1942. They were the crew of a Wellington bomber aircraft which made a forced landing during an attack on Tobruk Harbour. As soon as their aircraft had landed they took their water carrier and at once began their journey home through enemy territory. They walked about 450 miles.
