SIPE grenade

The SIPE grenade is a fragmentation hand grenade whose stated battlefield purpose was defensive: the account classifies it as a weapon for stopping an attack, not advancing one. Its most consequential appearance, however, comes away from the battlefield, when two grenades are concealed in addressed parcels as retaliation for a political defeat. The contrast between the weapon’s classification and its use makes it an instrument of intimidation—and a measure of how political conflict has entered Benito Mussolini’s newspaper office.

Design and Intended Use

The account distinguishes the SIPE grenade from the Thévenot grenade by both function and method of use. The SIPE required deliberate ignition after its protective cap was removed. Its fragmentation made it dangerous beyond the distance at which it could be thrown, a characteristic that the narrative uses to explain its defensive classification: it was suited to halting an enemy attack. The Thévenot grenade, by contrast, is identified as offensive. These are not interchangeable devices in the account; their different ranges and battlefield roles establish a distinction between holding ground and attacking.

That distinction sharpens the significance of the SIPE’s later appearance in parcels. The weapon described as defensive is used not to meet an assault in the field but to carry a threat into civilian and political life. Its meaning shifts with its setting: the account first defines it by military function, then shows it being enlisted in a private act of retaliation.

The Parcels in the Newspaper Office

After the socialists’ electoral victory and the defeat of Mussolini’s movement, Mussolini remains in the newspaper office as hostile shouts rise from the street. At his work table are a glass of milk, an old pistol, and a map of Italy marked with a tricolor flag at Fiume. He has editor Arturo Rossato handwrite the addresses of Emilio Caldara, Milan’s socialist mayor, and an archbishop on two spherical parcels wrapped in newspaper. The handwritten addresses are intended to thwart detectives’ investigations; the parcels contain two SIPE grenades.

The office scene places the parcels among ordinary and political objects rather than in a military setting. Mussolini stirs and drinks his milk beside the pistol while the crowd outside denounces him. The grenades extend the confrontation beyond the office: they are prepared for delivery to named public figures, and their concealed form makes the parcels part of the threat. The account identifies the decision as retaliation for the electoral defeat, not as an act of battlefield defense.

Intended Danger and the Threat of Use

Arnaldo Mussolini reacts by condemning his brother’s decision as criminal. The scene makes clear that the parcels are not merely an abstract display of military equipment: their contents are concealed, their recipients are selected, and the handwritten addresses are meant to impede an investigation. The SIPE grenade therefore connects a political grievance to a planned act with consequences beyond the men in the office.

Albino Volpi then reassures Arnaldo that a SIPE grenade sent through the mail presents no danger because of its fuse and detonator. This reassurance concerns the particular method of dispatch; it does not erase the grenades’ stated battlefield capacity or the deliberate decision to send them. The contrast leaves the parcels suspended between threat and claimed safety: their intended message depends on the presence of explosives, even as Volpi argues that mailing them makes them harmless.

Narrative Significance

The SIPE grenade’s significance rests on this tension between classification and use. Its technical description assigns it a defensive role, while the parcels transform it into a concealed instrument of political retaliation. The object also joins two contrasting images in the office: the old pistol, a visible weapon at Mussolini’s desk, and the grenades, hidden inside newspaper-wrapped packages. Their concealment gives the political threat a different form from the public shouting outside.

By returning to the grenade’s military function after depicting the parcels, the narrative makes the object more than a prop in a single episode. It shows how a weapon’s meaning is shaped by its circumstances: designed for defense in war, it becomes a vehicle for intimidation in the aftermath of an election, while its supposed lack of danger in the mail offers only a narrow, uneasy qualification.
