In 1947 he married his second wife, Elli Gatou (from Amfissa), following an "approval order for marriage" from the Air Force (as at that time its personnel needed approval for marriage), with whom he had two children, George (1948) and Constantine (1950). Until the end of the Greek Civil War, he served in Araxos with his last commander being the well-known RHAF pilot and holder of the Flying Cross, Group Captain Vassilios Kontogiorgos. On 22nd March 1946 he was transferred to the Administrative branch as a general duty officer and on 21 January 1950 he regained the specialty of Radio Operator - Ground Telegrapher. Zacharias was a supporter of the Uncrowned Constitutional Democracy, which, due to his temperament in political discussions, he found it difficult to hide (at that time Greece had something like a Constitutional Monarchy).  Just two years before, in 1948, his name was published in a list of 75 enlisted in the Air Force, who were targeted by an extreme right-wing underground mechanism within its ranks. This was done to intensify a climate of terrorism that had spread within the National Defense branches, aiming to discourage the enlisted personnel from voting for parties that were against the King. The list was published on 12th January 1948 in the newspaper "Ethnikos Agon", a "weekly political newspaper of the intransigent nationalists", with Leonidas Vrettakos, a member of the Parliament from the area of Laconia/Peloponnese, as its director.  The list included some well-known names such as Konstantinos Chondros (later Karamanlis's pilot), Ioannis Katsaros, Spyridon Diamantopoulos, and Athanasios Toregas, all of them accused of being either communists or friendly to the KKE (Communist Party of Greece). As a follow-up to the case, in November 1950, some unspecified "misconduct" penalized Spendos with a 6-month leave of absence. This "misconduct" was "attributed" during the first post-civil war elections, a period with a high political stake, so it almost certainly had something to do with his political views. During this period the terror by the loyalists to the king, against the republicans within the National Defense branches had intensified, with the centrist and neo-liberal democratic parties being accused by the pro-royalists of being Communist-friendly.
The oxymoron of course is that on 9th June 1949, and while he had already been targeted by the plotters, the service and the Chief of the General Staff, Group Captain Potamianos, had considered him ideal for a position in the intelligence office (A2 in Greece). Specifically, in the folder ΓΕΑ Α4/ΙΓ/ Αρ.Πρωτ. Α1510, it states the following:

"Given a classified memo from the A2 Directorate dated 8 June 1949, we appoint Flying Officer Spendos Dimitrios No. 265 as Cryptographic Officer of the Air Force General Staff to replace Lieutenant Valianos Michael No 5913 who is prevented from attending due to workload."

At the same time, Vassilios Kontogiorgos, in another document confirmed that during the Civil War Zacharias was away from the Front, in Araxos, and was serving excellently and according to the regulations under his direct orders, writing the following in the daily orders of 20th May 1949, attached to the folder ABA/72/PI/972:

"Expression of satisfaction to Flying Officer Spendos Zacharias, who has received today's transfer orders by the Ministry of Air Force. I express my satisfaction because for two years at the Araxos Air Base he has worked with zeal and willingness without ceasing, contributing the most to the general organization, management, and performance of the Air Force base."

The same confirmation was given much later, in 1984, by Brigadier General Theodoros Kleimakis in a statement to ΔΕΠΑΘΑ (Directorate of Victims and Disabled ex-Reserve War Veterans) stating the following:
 
 "Lieutenant Zacharias Spendos was an excellent officer of the Hellenic Air Force in terms of ability and ethos and with great resistance activity. Since 1949 he was discredited because of his democratic convictions and was eventually demobilized. The above is confirmed by my knowledge as his physical supervisor. Athens, 23rd March 1984".

In 1951, according to the Government Gazette 31-3-1951 and No. Bulletin 97/ Issue 3, he received the rank of Lieutenant, with retroactive effect (from 29th March 1944), which was the first recognition of his period of captivity and suspension as a period of service. However, he was discharged on 30 April 1952 "due to stagnation" after his service in Araxos. He remained in the Reserve until the end of 1953 when he was also discharged from the Reserve for "exceeding the age limit". This involuntary retirement was put to effect by the issued Order  No.1108/PRS/Y154 19/5/52 RHAF because he had been found stagnant for the second time by the Supreme Council, even though a year earlier he had been praised and suited for an important position. The real reason for his demotion, again, as was attested to several years later, was his political views. Although, since 31st October 1952 and at his request, he had been issued a certificate of his service in the ranks of the Air Force during the Civil War, this certificate was not accepted by the Court of Auditors to assign him the correct Pension Level Rank.  He was therefore granted a pension on 15th November 1952, that lacked the benefits to which he was entitled on account of his service rank and health issues caused by the parachute drop and his following captivity. It is worth noting that after the parachute injury, his treatment was neglected due to his captivity, and as a result, over the years his health deteriorated considerably.   Despite the constant applications he had made to the Air Force and the assurances he had received, he was never awarded a war disablement pension. The refusal was based because, at the time of his injury, he had not been examined by a doctor to obtain a certificate for his injury. After his discharge, he again served as a Radio Operator. At first, between 10th February 1954 and 6th June 1956, he worked on the OTE (Greek National Telecommunications Organization) ship that laid cables, the well-known "Thales from Miletus", which is now docked as a floating museum at Flisvos Marina. Then, always as a radio operator, he sailed on various merchant navy ships. Unfortunately, on a voyage to the Indian Ocean, he became very ill, and that had a serious impact on his already compromised health from his wartime hardships. Due to this health deterioration, around 1960, he began to experience severe mobility problems and after an investigative surgery, he was paralyzed. Zacharias Dimitrios Spendos passed away on 3rd July 1974, after 14 years of complete paralysis. He was buried in the 1st Cemetery of Athens. In August 1956, shortly before his paralysis, he achieved recognition for his service as a paratrooper, following a request to the Hellenic Air Force Command. Restoration to his rank was delayed until the moment when Vlassis Dedes brought to light evidence of the "Akrivoyannis case" that was part of the plot that framed also Zacharias. As a result of the revelations of the conspiracy and the recommendations of superiors, his patriotic contribution to the National Resistance was recognized. On November 25, 1986, he was awarded the Medal of the National Resistance 1941-1945 as a member of the E.D. Middle East. In 1987, 13 years after his death, following a request submitted by his widow, Elli Gatos, and after a thorough examination of all orders and documents, Zacharias Spendos was fully restored in terms of rank by the Committee for the Rehabilitation of Persecuted Employees and Military Personnel, under Decision No. 3974/1987, with complete integration into Article 20 of Law 1543/85. By Government Gazette 28/08/1987/172, he was retroactively promoted to the ranks of Squadron Leader (19/01/1950), Wing Commander (1/04/54), and Rear Admiral (8/05/57). It was a vindication not only for him but for his family as well. His son, Georgios Spendos, describes his father, Zacharias, with the following words:

"A character unselfish to the point of exaggeration, simple in behavior towards others. He made a companion of the man and not of his rank. His companions ranged from general, and professional to the laborer. He had a great sense of humor. However, what I noticed as a child who saw him constantly in bed, was a permanent melancholy. What struck me was that, despite all the injustices he faced, he never complained, perhaps his greatest flaw - his greatest virtue - was that he could not bear seeing others being wronged, not himself. He always took the side of the wronged and many times came into conflict with his superiors. Living with a paralyzed person is a difficult task with multiple problems every day and special needs. Our mother Ellie, who stood like a rock in the family by playing the role of both parents, managed to keep us together and made us forget the difficult times. We owe her everything and remember her with gratitude."
