Major General Gustaf Nils Oscar Rosenblad (1 August 1888 – 14 July 1981) was a senior Swedish Army officer.

[1] Rosenblad was commissioned as an officer in 1908 and was assigned as a underlöjtnant to the Svea Life Guards in Stockholm the same year where he was promoted to lieutenant in 1910.

He was a member of the Pension Board (Pensionsnämnden) from 1917 to 1924 and served as an officer candidate in the General Staff from 1918 to 1920, and studied law at University of Oxford in 1920.

Rosenblad then served as chief of staff of the Northern Military Command from 1930 to 1933 when he became major in Life Regiment Grenadiers in Örebro.

At the center of the scandal was Major General Nils Rosenblad, who had owned shares in the pro-Nazi Swedish newspaper Dagsposten, which received financial support from Germany during World War II.

Because Rosenblad was highly placed in the Swedish military command, he ended up in the eye of the storm, with persistent attacks in articles and petitions.

It was not made better by the fact that Rosenblad himself provided conflicting information to both Supreme Commander, General Helge Jung and Defence Minister Allan Vougt.

The Chancellor of Justice Olof Alsén [sv] stated that Rosenblad had indeed been careless when it came to the shareholding, but that there was no indication that he would be politically unreliable.

At a meeting on 8 April 1946, Minister of Education and Ecclesiastical Affairs Tage Erlander pointed out that the major general's forgetfulness regarding the shareholding was incomprehensible, especially as it emerged that he was well aware that the newspaper received subsidies from Germany.

When the Supreme Commander and the Chief of the Army also formally asked Vougt to dismiss Rosenblad, he did as requested and left his post.

The minister who took the most offense to the affair was Per Edvin Sköld, who believed that Rosenblad had suffered a miscarriage of justice and that the Swedish government had been run over by the communists.
